ISSUE-177: Rephrase "adding meaning" in Syntax specification

Sandro Hawke raised concerns [1] about the use of the phrase "adding
meaning" in the syntax spec.

I edited the spec to remove all those phrases. The diff is here:

As agreed in the last telecon, I send this email to inform everyone about
this change. If no concerns are raised within the next 24h I will go ahead
and close the issue.


Cheers,
Markus
