Re: Correction to my last posting Re: dependent and independent intervals, proposal to toss out text2interval. Was re: about emp (was: Motion 42:no)

Vincent,

Thank you;  that clarifies it (I think).  If I understand
you correctly, you are saying that
some of our proposed wording might prohibit certain
possibly desirable extensions.

Quaternion arithmetic would be completely out of the scope of
the standard. Here, the behavior of text2interval is involved.
For instance, if the standard says that the implementation
shall return an error on any string that is not in the specified
format, any extension would be forbidden. A different function
may not be satisfactory. For instance, a user may just need
something like

   text2interval(interval2text(x)) contains x

without knowing whether extensions are used internally.
