Oxygen XML Author Professional V21.1

DITA Authoring

• View the Hierarchy or Dependencies of References in DITA Resources - The Hierarchy/Dependencies view can now be used for DITA resources to display the hierarchy or dependencies for DITA resources. It will show direct references for DITA resources, such as maps and topics, as well as media resources that are directly referenced in topics.
• Quickly Search for Similar Topics - A new action (Find Similar Topics) is available in the DITA menu that can be used to quickly find related topics that can be added as related links.
• Improved Behavior when Pasting Table Content - When copying a multiple selection of table cells and pasting them outside the table, a new table will be created. When pasting into space-preserved elements, the cell content will be pasted as plain text.
• Specify that an Attribute only Accepts a Single Value in a Subject Scheme Map - You can now use outputclass="single_value" when binding an attribute to a key in a Subject Scheme map to specify that a certain attribute only accepts a single value at a time and the attribute will be presented in Oxygen with radio buttons instead of checkboxes. Also, a validation error will be displayed if an attribute defined to accept a single value has multiple values in the content.
• Improvements When Searching References to Images - When searching for references to images, the reported results have been improved. For example, if the image reference is defined with an href attribute, all direct references to that image file are reported, but if it's defined with a keyref attribute, all instances where the key is used are also reported. Furthermore, if the image includes an id attribute, all links to the specified ID will also be reported.

Visual Editing

• More Highlighting Color Options - When highlighting content in the Author visual editing mode, you now have more color options to choose from.

CSS

• Support for CSS Level 3 Functions target-counter and target-counters - The CSS level 3 functions target-counter and target-counters are now fully supported as values for the content property to retrieve counter values and display information obtained from a target at the end of a link.

CSS-based PDF Publishing

• New Option to Apply Framework CSS in the XML to PDF Transformation with CSS - The XML to PDF Transformation with CSS scenario now includes an option to apply CSS stylesheets that are specified in the framework (in the Document Type configuration CSS subtab). They are applied in addition to any CSS files referenced directly in the document and any custom CSS specified in the CSS URL field in the transformation scenario.
• Generate TOC at the Beginning of Each Chapter - For the DITA Map to PDF - based on HTML5 & CSS transformation scenario, a new parameter (args.chapter.layout) can be used to generate a mini table of contents at the beginning of each chapter. For more details, see Table of Contents for Chapters (Mini TOC).
• Support for Various Languages - The DITA Map to PDF - based on HTML5 & CSS transformation scenario now supports numerous languages, including Chinese, Arabic, Russian, Spanish, and more. You simply need to set the xml:lang attribute on the root map or use the default.language parameter.
• Style Topics Depending on Their Role - For the DITA Map to PDF - based on HTML5 & CSS transformation scenario, the topicref class attribute values are passed by the transformation process onto the corresponding topic elements from the merged map content. You can use this to style topics with different roles, such as preface, notice, abstract, or copyright. For more details, see How to Style the Front Matter and Back Matter Topics.
• New Deep Numbering Options - For the DITA Map to PDF - based on HTML5 & CSS transformation scenario, two new numbering types are now available that can be controlled by a transformation parameter. The deep-chapter-scope parameter can be used to restart the numbering of pages, figures, and tables at the beginning of each chapter (and adds the chapter number to the titles of figures and tables). The deep-chapter-scope-no-page-reset parameter is similar except page numbers do not reset at each chapter.

HTML

• Specialized HTML Editor - Oxygen now includes a specialized HTML editor with various editing features for files that have the html or htm file extensions. Features include a new document template, folding support, syntax highlighting, and more.
• Content Completion - The Content Completion Assistant offers proposals for elements, attributes, and values that are valid at the current editing location, provides annotations for many of the proposals, as well as links to the HTML5 specification.
• Validation - Oxygen includes a built-in validator used for validating HTML documents. It is based upon the W3C HTML Validator and the HTML documents are validated against the W3C HTML5 specification.
• Outline View - The specialized Outline view for HTML documents handles void elements or elements that are not closed, and presents the tree structure of the HTML document correctly.
• Encoding - For HTML documents, the encoding is detected automatically based on the value specified in the charset attribute of the meta element.

Content Completion

• Show Content Completion Annotations in Various Languages - You can customize XML files that are used for annotations in the Content Completion Assistant to display the annotations in various languages. For more details, see the Translating Annotations section of Customizing Annotations in the Content Completion Assistant.
• Translation Support for Content Completion Annotations Using the ${i18n()} Function - When using a configuration file to customize the Content Completion Assistant, you now have the ability to translate the annotations for elements using the ${i18n()} function.

Other

• Improved Editor Variable Interpretations - The editor variable interpreter was enhanced. For example, when mixing editor variables in XPath expressions, Oxygen now allows nested editor variables (such as oxy_xpath + ask + answer).
• Content Completion and Syntax Highlighting when Configuring Framework Actions - When configuring custom actions for frameworks in the Document Type Configuration wizard, the Activation XPath editor now includes content completion and syntax highlighting to make it easier to write the XPath expressions.
• XPath Function That Returns the Platform - When configuring custom actions for frameworks in the Document Type Configuration wizard, you can write an activation XPath expression for each activation context. A new XPath function oxy:platform() was added that returns the current platform that Oxygen is running on. It can be used, for example, if you want to enable or disable an action in the Author visual editing mode depending on the platform.

API

• Multiple JavaScript Modules Allowed in WorkspaceAccessJS Extension - JavaScript-based plugins can now include multiple modules of JavaScript files in the plugin. You can declare functions that can be used in the main WorkspaceAccessJS JavaScript file and use those external script files as a library of functions.
• Project API Improvements - The new API ProjectChangeListener can be used for notifications when there are changes to the project (for example, when another project is opened). Also added addProjectChangeListener, removeProjectChangeListener, and getCurrentProjectURL methods in the ProjectController API.
• UI Components Factory - The OxygenUIComponentsFactory API was added and it is meant for easily creating UI components with the same appearance as the ones used in Oxygen.
• Set Initial Directory - The WorkspaceUtilities.chooseDirectory(File) API method was added, and it can be used to browse for a specific directory, starting from an initial one.
• Faster Processing for API DITA Keys - The KeyDefinitionManager.isPassKeyTargetReferencesThroughXMLCatalogMappings API method was added, and it can be used to avoid passing key reference URLs through XML catalog URI mappings to speed up conversions when an external DITA keys resolver is being used.
