Embedding HTML Content in DITA Topics
The DITA Open Toolkit that comes bundled with Oxygen XML Developer plugin includes a pre-installed plugin that allows you to embed well-formed HTML content directly in a DITA topic.
For example, suppose you wanted to embed a YouTube video directly in a DITA topic.
The DITA topic would look like this:
....
<foreign outputclass="html-embed"><![CDATA[
                <iframe width="420" height="315" 
                  src="https://www.youtube.com/embed/qepRkQxhTX" 
                  frameborder="0" allowfullscreen="true">
                </iframe>
                ]]></foreign>
....
         The converted HTML output would look like this:
........... <iframe width="420" height="315" src="https://www.youtube.com/embed/qepRkQxhTX" frameborder="0" allowfullscreen="true"> </iframe> ............
The plugin is also available on the oxygenxml GitHub projects page.
