FACE11 — Delete IDLxxxx elements removed from FACE 3.1/UDDL Standard

Related to and part of Issue FACE 11-2: Update standard to FACE 3.1

When FACE 3.0 transitioned to FACE 3.1 (with the newly-extracted UDDL v1.0 standard included for the FACE Data Model), multiple unused or unnecessary metamodel elements with the prefix IDL were removed from the FACE Metamodel. Remove the corresponding stereotypes from the FACE 3.1 standard.

Note that deleting the corresponding stereotypes implies also removing any references to the deleted stereotypes, including in diagrams.

Original Issue text, INCORRECT: metamodel elements deleted from the FACE 3.1 standard are:
IDLBoundedString
IDLCharacterArray
IDLUnboundedString

Corrected Issue:
Delete CharArray (will be replaced by renamed IDLCharacterArray)
Delete FACE_BoundedString (will be replaced by renamed FACE_IDLBoundedString)
Delete FACE_IDLUnboundedString
