Using BaseX77-20130417.002917 though I don't think that's relevant to the question.

This may well be an inherent property of the library being used to do validation, but right now, when I use validate:xsd-info, I get error messages that look like:

Error: 25:59: cvc-complex-type.2.4.a: Invalid content was found starting with element 'link'. One of '{bold, footnote, italic, superscript}' is expected.

These identify the location of the error by line and column number, which is great for code and less than helpful for XML content, since any format-and-indent getting applied to the XML file destroys its usefulness.

Is is possible to have the error return a node identifier of some kind, instead?  

/root/bucket[2]/block[4]/para[3]/emphasis[4]

sort of thing?

Thanks!
