pub.schema:validate not validating xsd:choice

Hi Team,

We have xsd:choice element between 2 fields in our request,but we are getting schema validation true
even if both fields are populated with value.
We are passing fully Qualified Document Type name to conformsTo field.also tried passing schema name ,got error like
"[ISS.0062.9029] The schema domain of the conformsTo object must match the schemaDomain parameter of schema ".
but schema domain is set to Default in both objects .
