Function that is called when a problem event occurs.

Parameters:

where - Either and XMLPARSER, XSLPROCESSOR, or QUERYENGINE.

classification - Either ERROR or WARNING.

styleNode - The style tree node where the problem occurred. May be null.

sourceNode - The source tree node where the problem occurred. May be null.

msg - A string message explaining the problem.

lineNo - The line number where the problem occurred, if it is known. May be zero.

charOffset - The character offset where the problem, occurred if it is known. May be zero.
