They have an [owner element] instead.  This corresponds to attributes
not being considered [children] of their elements.

Presumably you mean whay do we do it that way rather than having
entity information items containing the content.

The idea is that the 90% case is to access documents with all the
entities expanded.  It should be *possible* to reconstruct the
entity structure, but it must be *easy* to access the logical structure.

Both these issues are discussed in the XPointer - Infoset liaison
statement, http://www.w3.org/TR/NOTE-xptr-infoset-liaison.
