I think this is TRT.

So, I have a master impnotes.xml (<book>)) file which includes many
others via external entities (should I convert them to xincludes?).
I also have clisp.xml (<refentry>) with
<olink targetdoc="impnotes" targetptr="source-files"/>

DIUC that the above olink will turn into

<xref xlink="urn:impnotes#source-files"/>

To support olink, I have target.database.document files.
Will I be able to re-use them?

When will this be supported?
When will I have to switch to docbook5?
(i.e., when docbook4 will be deprecated?)

Thanks again!
