I validate XML files vs. a schema asfollows:

    xmlSchemaValidateDoc(validSchema, pDoc);

However, in ErrorCallback and WarningCallback I only get general
info about
the failure, but without the line number. 
It it's very helpful to tell the user that there is an error in
element, when his XML file contains 100 such elements.

Is there a way to tell the exact error line number?

 Obviously not with that API. Use the xmlSetStructuredErrorFunc()
from xmlerror.h to register a global structure error handler, then
you should get the node where the error was generated.

  oh, of course.  _obviously_ not.  No one would ever think that a
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
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
