Data types for an unstructured (BLOB) message

A parser is supplied for the body of a message in the BLOB domain; it associates each field with a specific data type.

An unstructured (BLOB) message has the data types shown below:

Data type of the element Represented as
BLOB BLOB
UnknownParserName CHARACTER

The UnknownParserName field, if present, contains the class name of the parser chosen in preference to the BLOB parser. This information is used by the header integrity routine (described in Parsers) to ensure that the semantic meaning of the message is preserved.
