The second issue above (beginning with "I also noticed the =
following...") is
not reported in Sandy's bug report.

Also, I think the problem is narrower than what is reported by Sandy.  I
don't see any problem in the XML representation and in the mapping from =
the
XML representation to the schema components.  The only problem that I =
see is
entirely at the schema component level, and is the way that the Particle
schema component's {max occurs} property is specified.  It should really
have been "Either a positive integer or unbounded".

I would like to reply to Sandy that the two following things are very
different:

1) the attribute "maxOccurs" of certain elements in the XML =
representation
of a schema;
2) the property {max occurs} of a particle corresponding to that =
element.

The former is allowed to be "0", the latter is not allowed to be 0.
