UPDMRTF — DMM is non-normative but appears to be nomative

This document refers to “DMM” which is defined as non-normative Annex A. However, it seems to be Normative. Besides, according to the text, it is necessary to refer to the colour legend. However, I couldn’t find the legend.

Clarify this sentence. If those were Normative, move DMM to the body parts.

Response,
add colour coding legend and explanations.

The DMM is intended to be informative and was used to develop an understanding of the foundational concepts from which the UPDM profile evolved. It remains useful for understanding the architectural concepts required to implement UPDM. It is expected that UML and SysML tool vendors who implement UPDM would implement this profile rather than the DMM; however, it is possible non-UML tool vendors may wish to implement UPDM in their by tool by following the DMM.
In annex A delete the second paragraph starting “Note that the” and replace with the text and diagrams below.
Note that the diagrams rely on color to aid the reader in understanding the model. Please refer to the legend below to understand the diagrams.
The following is the legend of element colors used in the DMM and what they denote.
