In 'somefile.xml', I found that I have to be able to point to the DTD as
follows:
<!DOCTYPE somenode PUBLIC "-//Some DTD//EN"
"some/hardcoded/path/somedtd.dtd">
The reason I have to hardcode the path is because the DTD is not located
otherwise.
Really, I have two choices: (1) to completely leave out the DTD, or (2) to
hard-code it.
I don't like either choice. I want to have the DTD, but I don't want to have
to hard-code it, either.
What happens when I don't hard-code the DTD is that the system generates a
TransformerException (see extract of core.log below) and won't return any
value (or maybe returns "null", which for all practical purposes is the same
thing in this case).
In other words, <xsl:value-of select="document('somefile.xml')/somenode"/>
returns null, when it should be returning some value.

Is that a hint? ;-)
If so, tell me where to look, and I'll see if I can make the time to look
into that some day.
Thanks!
