At the PRECIS WG session in Paris, we had quite a discussion about
spaces in user names. Alexey maintained that this must have been
included in SASLprep (RFC 4013) for a good reason, but the reason
wasn't clear to folks in the meeting. So I have a few questions:

1. Do SASL user names really need to include spaces?

2. If SASL user names do *not* need to include spaces, would it be
fine to re-use the PRECIS NameClass for simple user names in SASL?

3. If SASL user names *do* need to include spaces, would it be fine to
define simple user names in SASL as a space-separated list of
NameClass entities?

Option #3 seems preferable to (a) specifying that the PRECIS NameClass
needs to include space (to which there was a lot of resistance during
the PRECIS WG session), (b) enabling folks to superclass PRECIS string
classes (to which there was also a lot of resistance), or (c) severely
subclassing the PRECIS FreeClass to be something like NameClass+SP.
