Are you saying we can't do something like depends="a and b", because
instead of spaces we'd need to do depends="a%20and%20b"? If that's
true, it's obviously no improvement over depends="a&amp;b". However, I
can't find any reference to the requirement to escape embedded spaces
in XML attribute values. In fact, I can create a textarea in my theme
with name="spacey text area", and it works fine.

As for getting confused about the "or" in "color", I think you could
deal with that by splitting the string on " or " instead of "or".
These operators always come between two names, so they must be
surrounded by spaces. Now I suppose someone might try to name three
widgets "a", "b", and "a or b", in which case depends="a or b" would
be ambiguous. But you'd have the same issue if someone named a widget
"a|b", so this problem isn't specific to the word forms of the
operators.
