Re: Identify Common Purpose - resolving issues

> Nice work but one thing is that I see a limitation in “for each
user-specific input field” if we want to expand this SC to also apply to
NON user-specific input fields (or even links / buttons)

I'm guessing this space is in such a state of flux anyway that the SC
language will be different in future versions whether or not we figure out
an elegant expansion path.
