But what does it mean, really, for an attribute to be 'in a namespace',
separate from that attribute appearing (or being declared in an ATTLIST as)
within the scope of a particular element? Are there qualities which we are
to imagine that an attribute draws, or inherits, from a namespace which
influence its meaning or its usage in any way comparable to what that
attribute draws from its dependence upon the particular element which it
modifies? And if not, is Simon's suggestion not an appropriate
acknowledgment of the power exerted upon an attribute by the element upon
which it must depend?
