bccing www-tag as it's not an appropriate alias.

Rajesh,

There are several options:

1.	Use restriction rather than extension ( you want to restrict the
wildcard to be a particular element ). 

2.    Pass the SOAP 1.1 schema and the schema for SenderId and
DocumentID elements to you validator. A good validation tool will
validate correctly. 

3.	Copy-and-edit the SOAP 1.1 schema, adding an import for your
schema and changing the wildcards to element references.

Regards

Martin Gudgin
