  oh, of course.  _obviously_ not.  No one would ever think that a
schema
validation error callback would be handed the line number.
For those of us who don't know everything I submitted a bug to improve

the docs for the xmlSchemaSetValidErrors() function so it references
the 
more useful xmlSetStructuredErrorFunc(). (#142760)

  If there a function that will take the xmlError structure and format
a pretty error message?  Does the message field in the xmlError 
contain the file and line number, or is that just the basic error
info?
