doc-available is not the same as file:exists() - it will only be true
if the document could be read successfully with doc() (and of course to
dettermine this, the XSLT processor effectively does a doc() behind the
scenes, and then probably has to keep it in memory in case it changed
externally).

Also make sure your XSLT didn't create the document using result-
document... You can't write to the same URI more than once in the same
XSLT run.

Without seeing the exact error message it's hard to be sure.
