Checking before reporting a bug with "XRef to nonexistent id: "

[Johan Persson <johanp@aditus.nu>]

Hi,

Before I submit a minor bug I just wanted to check that this isn't already known 
(I searched DocBook bug list but couldn't find anything similar.)

I'm using Docbook 1.74.0 with "html.xsl" transformation (the same results
happens with onechunk.xsl)

Basically I get the following error message when running either xsltproc or 
Saxon 6.5

"XRef to nonexistent id: "

This happens when I reference an Id for a table in the title of a figure.

However this seems to be a bogus error since the links are generated correctly.
The following small example reproduces the problem when run with Saxon or 
xsltproc. A tried to keep it as small as possible but still a valid
docbook document.

                </para>

Is this a known problem ?
