An empty MFString array would have no values. Now that is an interesting one
we didn't discuss today!!!
According to the current standard it would be simply [''], i.e. two single
quotes or apostrophes. However, if we accept the changes discussed today,
one of which was that an MFString field with only one value could dispense
with the outer set of quotes and be encoded as an SFString, then that could
present a dilemma. It would mean that it could be interpreted as a single
value, which was the empty string, or an empty MFString array. These are not
the same things, and so this case would require specific wording in the
text, for clarity.
Thanks again, Yves,

Excuse me if I've missed it, but how do you specify an empty MFString array?
If double quotes are optional, '' (empty attribute value) would mean an
empty SFString, i.e. [""] if an MFString is expected, not .
