Hi Glen Thanks for taking the time to take a look at the source code.
And as to your questions 1. The QualifiedName is there because after you do a XmlSchema.compile(..) all the Types are supposed to be obtained form XmlSchema.getSchemaTypes(). This would include any types from the schema that is imported. In this a localname alone is not sufficient. But this feature viz. compile has not been implemented :-( 2) We haven't considered a schemacontext class. But I would think of the schema context as being a new schema object with all the other required schemas being imported( am I right ??? ). If so implementing the compile method would solve the problem you are trying to address. 3) Yes we could want to contribute this code to apache. But I would not think it should be a totally separate project by itslef till a lot of things are sorted out.( for eg. the compile method). I had spoken to Dims about this and he also feels the same. Use it in axis for sometime and if there is a need and the module is mature enough then we could think of a different CVS tree And we are also looking forward to see axis use this schema module :-). I hope I have answered all your questions Thanks.

A few comments about this library, first a couple related to the code in particular, and then one about the process of integrating it with Axis. In general, this looks great. Questions: 1) Why bother to keep all the objects in an XmlSchema referenced by QualifiedName? For a given XmlSchema, you're always defining things in only one namespace (targetNamespace). I would think you could just punt this and look up only by local name. 2) Have you considered a "SchemaContext" class which could hold a number of XmlSchema objects? This would be perfect for something like parsing WSDL where there are multiple <schema>s which need coalescing. It seems like this would really be the place you'd want APIs like context.getType(QName typeQName) or context.getElement(QName elemQName). 3) Would you want to contribute this to Apache wholesale (org.apache.xml.schema or something), or keep it maintained by Infravio? I see a lot of value in this code, but also a lot of places we might want to add accessors, tighten up APIs, etc. - if we were all working together to make this library work, I think we could do some great stuff, but I'd be a little less excited if we couldn't have an editable copy in CVS. Thank you *very* much for bringing this code to us, I hope we can indeed move forward taking our schema-handling out of the stone age. :) --Glen > -----Original Message----- > From: Vidyanand Murunikkara [mailto:Vidyanand@;infravio.com] > Sent: Tuesday, November 05, 2002 1:56 PM > To: [EMAIL PROTECTED] > Subject: XML Schema support for Axis (Contrib from Infravio) > > > Hi > > Infravio would like to become actively involved with the Apache Axis > project by providing an XML Schema Parser module.
