Schema reporting tools - XQuery use case?

[George Cristian Bina]

The commercial Saxon 9.2 EE (previous Saxon-SA) XML Schema processor has 
a command line switch that outputs an XML file with the schema 
information in a format suitable for further processing.
For details see the -scmout:filename option

George

But there is another important technology, of course, XML Schema: though its use is often reduced to document validation or data binding, schemas offer a great wealth of static information about (valid) documents. I am sometimes amazed how merrily this information is ignored, especially in projects that have to deal with very complex schemas.

(I am _not_ thinking of graphical representations as offered by XML IDEs unless they are accompanied by serialized versions appropriate to serve as input for further processing.) Some examples were: a tree representation of document structure, a list of valid data paths, a mapping of element and attribute names to the governing type, a mapping of type names to data paths.
