Re: [docbook-apps] XInclude problems after upgrading docbooc-xsl

["Bob Stayton" <bobs@sagehill.net>]

This problem can occur when you try to use the same olink target data for 
HTML and FO outputs.  When you generate a target.db file, the <xreftext> 
element contains the fully formatted text to be used for an olink to that 
element, including any appropriate inline formatting markup.  If you 
generate a target.db with an HTML stylesheet, you will get <i> in your 
chapter data.  If you generate target.db with an FO stylesheet, you will get 
fo:inline in your chapter data.

So if you generate the target.db file with an HTML stylesheet, and then you 
use that target.db file with an FO stylesheet, you'll get the results you 
see.  So if you need to generate both outputs, you need to keep separate 
target.db files, or regenerate them each time you process your documents.
