To make this fully supported by schemas, one would need a way to
indicate in schema rules for the cardinality, etc., of the "properties
of properties."

But there is also a versioning issue. Since adding such meta-data as the
last-modified date after the fact is a typical usage, attributes today
allow such annotation with less disruption to existing readers.  E.g. 

<email last-modified='2005-02-02'>fred@somewhere.com</email>

But this only works to one level.  One cannot add an attribute to that

One could imagine a future version of XML that treated elements and
attributes with more parallelism, and allowed attributes to have
structure, perhaps with an element-like syntax, as in:
