4F031097.40402@i..." type="cite"> A related issue - I think it's related? - is handling binary content.  We have run into a number of use cases where it would be convenient to be able to process images - at the very least to test for their existence, but maybe also read in and write out unchanged - but doc-available() and doc() in xslt don't allow this, I think.  We've worked around with java extension functions in Saxon, which is fine, but wouldn't it be better to work in some binary support (does unparsed text do this? not sure) into the language.
