Link not created in the XHTML output for a xref/@keyref element

[sorin-ristache]

I try to insert a link by enclosing text with xref:

<xref keyref="video">video title here</xref>

The key is defined in the map as:

<keydef keys="video" href="videos/Change_Tracking.mp4" 
      format="mp4" processing-role="resource-only" navtitle="TITLE"/>

The problem is that the text "video title here" is rendered as plain text instead of link in XHTML output.

If I add the scope="external" attribute to the keydef the link is created correctly but now the video resource is not copied to the output dir anymore though I added the .mp4 extension to the resource list in file DITA-OT/lib/org.dita.dost.platform/plugin.properties.

Keyref processing skips this key because the target file doesn't exist. The code should not test if the target exists when format is not DITA.

This is a bug in the processing logic. The spec says

attributes... are combined as for content references

Thus the format should be copied to the xref element. If the xref were to already have a format attribute, the attributes of referencing element (xref) will override the same attributes on the referenced element (keydef).

Fixing this will change other keyref processing behaviour and may affect users who expect the old incorrect behaviour. For example, if you have

<topicref keys="blatexample" href="blatview.dita"/>

and

<xref keyref="blatexample" href="http://www.google.com" scope="external">Google</xref>

The old effective output was

<xref href="blatview.dita">Google</xref>

but after the fix the output will be

<xref href="blatview.dita" scope="external">Google</xref>
