Namespaces and Namespace Prefixes
JUMP is based on the JSON protocol which does not understand or directly support XML namespaces. Namespaces are used heavily in SOAP and SOAP headers.
To correctly identify the elements of a SOAP header, you must:
Use the XML namespace prefix that is defined in the schema for that element as the prefix for the property name in the serviceHeader object. In the previous example, ser is the namespace prefix defined for SOAP headers in the schema for this service.
Enclose the fully-qualified name (the namespace, colon and element name) in quotation marks for each SOAP header element to ensure that the colon in the qualified name is not misinterpreted as part of the JSON syntax. For example, "ser:Username" is a property name but ser:Username is a property (ser) and value (Username) in JSON syntax.
