Hi there!
I want my PDF to have internal links to the references at the end of the file.

For example, my XML is:

<xref ref-type="bibr" rid="ref1name">Author name </xref>

At the end of my PDF I have the info about each author, tagged as this:

<ref id="ref1name"> info about the author </ref>

And my CSS:

xref[ref-type="bibr"] {
	content:target-content(rid);
}

This does not seem to create the proper links. Any ideas how to do this?
Thanks in advance!

As in clickable links? This will require using the prince-link property:

xref[ref-type="bibr"] {
    prince-link: attr(rid, idref)
}

Exactly just like that!!!
Thanks again Mike!!!!

Thanks for this feature!!!
