[xslt] entity substitution... broken?

[Michael Rothwell <rothwell holly-springs nc us>]

I'm using the current Win32 versions of the libraries, available on 
Igor's website.

I have a template file that defines a number of entities used in the 
templates. If one of the entities isn't there, errors are generated 
because the entity cannot be resolved. All well and good. But if the 
entity is there, it doesn't make it into the (html) output. This program 
worked either earlier versions of the Win32 Libxml2 and libxslt 
libraries, and I can't find the magic switch. Any suggestions?
