runtime issues

Modeltools parsers contain a variety of exiting dialogs that announce that there is a really, really bad internal problem in the parser. These are software development dialogs and are, hopefully, only of historical interest.

But parsers also contain exiting dialogs that launch in response to the document that is being parsed. The most common of the document errors is that the document contains an XML tag that has a faulty name or is in the wrong location. The parser's response is shown below.

The fix is to edit the document to conform to the XML schema in use.
