The error messages about "xref linking to  has no generated link text."
seem to be caused by a bug in handling of instances of "<citation><link
linkend="ansi-cl">ANSI CL standard</link></citation>" in your source. If
you can open a new bug about it, I'll make sure to follow up with Bob. He
made some significant changes to the code for xref handling recently.
Those changes seem to have introduced the problem you're seeing.

Sam,

I tested Bob's change with your clisp.xml built from your latest CVS, and
it seems to fix the "xref linking to has no generated link text" problem.
Can you please test with the lastest snapshot and confirm?

I checked in fixes for html and fo inline.xsl to handle citations that
link to biblioentry based on abbrev element matching.  I simplified it to
not call the xref template since that is not needed in this case.

A fix for this issue has been added to the current codebase.
Please test the fix with the latest snapshot from:

  http://docbook.sourceforge.net/snapshots/

I'm also not able to duplicate the error with the given sample document. 
Was a customization involved?

Also, the bug report mentions version 1.69.1 of the stylesheets, but that
error message was not introduced until after 1.71.1, so I presume we are
talking about the snapshot release, right?

hmm, I now don't seem to be able to reproduce this with the minimal test
instance I put together. I guess I made it too minimal. I'm now not sure
that the issue of it having multiple Abbrew instances is actually a problem
or not.

@linkend and @xlink:href are both valid on Citation in DocBook 5, but not
in DocBook 4. So if want to validate against DocBook 5 instead of DocBook
4, you could move the @linkend to the citation.

Anyway, we still have a bug in the stylesheets that we need to get fixed.

http://docbook.org/tdg/en/html/citation.html does not list @linkend or
@xlink:href attribute on the citation element.
are they allowed?
if so, I can just replace "<citation><link linkend="ansi-cl">ANSI CL
standard</link></citation>"
with "<citation linkend="ansi-cl">ANSI CL standard</citation>"

Problem seems to be the fact that the Biblioentry in the test document has
multiple Abbrev elements:
<abbrev>ANSI CL</abbrev><abbrev>ANSI CL standard</abbrev>

Not sure why it does or what the expected behavior should be when it does,
but it is valid to have multiple Abbrev instances there, so it seems like
we should be handling it.

And along with that, there is still the issue of the error message not
looking for the linkend ID on the correct element (it's looking for it on
the Citation, but should be looking for it on the Link).

Pasted in here and also uploaded/attached is a minimal test case that
demonstrates the problem.

The root problem appears to be that the xref (named template) code is
looking for a
@linkend or @xlink:href attribute on the citation element, but in this
case
the linkend attribute is actually on a link element that's a child of the
citation.

I'll try to upload a minimal test case that demonstrates the problem.
