SYSML2 — Do not use abbreviations for key word in SysML v2/KerML textual concrete syntax

I would like to recommend, that abbreviations are not used in key words for the SysML v2 textual notation (resp. KerML). A good example is the key word "def" instead of "definition".
Why it is here an abbreviation and other (longer) key words are not?
To make the textual notation more consistent for users, eliminate all abbreviations and write it out.

No Change

While most keywords in the SysML textual notation are, in fact, full words, It was specifically decided in the design of the notation to use abbreviations for certain long words that are expected to be heavily used, particularly if there is a common practice of abbreviating them in other textual notations. This includes keywords such as def, ref and enum. It is not considered desirable to change these to use the considerably lengthier full word forms.
