libvirt? I guess you meant libxml2 ;) Yes, the construct may be unusual. I bumped into it though when trying to validate an OpenDocument document in strict mode using the RelaxNG schemas from OASIS. http://www.oasis-open.org/committees/download.php/12569/OpenDocument-schema-v1.0-os.rng (On line 13737) (Note that you have to validate using http://www.oasis-open.org/committees/download.php/12569/OpenDocument-strict-schema-v1.0-os.rng, which includes the aforementioned file and sets it up for strict validation, for that line to kick in.) What do you say, do you think it's a hard thing to fix? This guy (Jos) in the KOffice project is working on an automated test harness for our conversion of other office formats to OpenDocument where he first converts to OpenDocument and then run a validation on the resulting document. This is how the problem was found. It would be nice if the OpenDocument schemas were supported by libxml2 since libxml2 is so much more widely available (and leaner!) than Jing.
