Clause: A.5

Paragraph: SCL_Communication.xsd

Issue

The restrictions for the P elements could be improved to find syntactical errors during a schema validation.
For example, the TSEL/SSEL/PSEL values are pairs of hexadecimal digits but the schema allows odd numbers of hex digits.

Proposal

Update the following types with contents of the attached file:
tP_OSI-NSAP
tP_OSI-TSEL
tP_OSI-SSEL
tP_OSI-PSEL
tP_OSI-AP-Title
tP_OSI-AP-Invoke
tP_OSI-AE-Qualifier
tP_OSI-AE-Invoke
