Re: [docbook-apps] xlink:title not getting into HTML, 1.77.1

Hi Jennifer,
> namesp. cut : stripped namespace before processing

This indicates that the stylesheet being applied to your DocBook 5 document 
is the non-namespaced version.  That stylesheet cannot match on namespaced 
elements, so it first converts the DocBook 5 document to DocBook 4 before 
processing.  In doing so, it converts external links to <ulink> and that 
element does not support xlink:title attributes.

I suggest you instead process your document with the namespaced version of 
the stylesheets with are meant for DocBook 5, (with "-ns-" in the directory 
name).  If you are using an old version of Oxygen, it may not have them, but 
you can download them from SourceForge:

https://sourceforge.net/projects/docbook/files/docbook-xsl-ns/1.77.1/

With that stylesheet, it will not convert your link to ulink, and it will 
output the title attribute from the xlink:title input.
