I have further edited the proposal to 

4) remove default values from the schema, and
5) allow double-hashing for the document passwords as well as the table
passwords
6) change the default value for table:protection-key-digest-algorithm-2
so that an absence of this attribute means the application should not
double-hash the password.

I would at least like someone to confirm that it's okay to use
the http://www.oasis-open.org/committees/office/legacy-hash-excel URI
to identify the legacy Excel hash.  It's a made-up URI and doesn't lead
to any existing content.  I made that one up only because the
table:protection-key-digest-algorithm attribute (and the -2 variant)
requires an URI.

Thanks.
