Re: use of XSD

Is it possible to read the XSD into some kind of xml object and access the simpleType enumerations to extract the code AND description

..NET 1.x has a schema object model (SOM) implementation with XmlSchemaCollection
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemXmlSchemaXmlSchemaCollectionClassTopic.asp>
and XmlSchema
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemXmlSchemaXmlSchemaClassTopic.asp>
so you can indeed load a schema and then have an object model you can navigate. But with the complexity of possible schema structures the general navigation is also rather complex. Enumeration is just one possible facet.
See
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconxsdschemaobjectmodelsom.asp>
for details about the SOM.
