PRB: XLANG Scheduler Does Not Understand the Target Namespace (321773)

SYMPTOMS

• You can validate an XML document with a target namespace in BizTalk Messaging Manager. However, if you try to validate the same XML document against the same schema in the XLANG Scheduler, the validation is unsuccessful, and you receive error messages that are similar to the following in the BizTalk Server application log:

  The Message Queuing message was not successfully validated against the schema that was provided. 
  Check the schema and the schema path.

  Message name: LoanApplication 
  
  Validate failed because the root element had no associated DTD/schema.

• The data flow between messages in XLANG may work not as expected if the message specification has a target namespace. For example, if you map a constant to a message field on the Data page of the Orchestration Designer, the message field may not be populated as expected when the document is processed if the message specification for the document contains a target namespace.
