Michiharu's proposal does not "break the notion of bag of same
typed elements".  He proposed DataType "anyURI" for the reference
to the entire document, and DataType "xpath-expression" for the
reference to the particular portion of the document to be
accessed.  A ResourceAttributeDescriptor must include the
DataType, and so the resulting bag would only contain the
resource-id Attributes of the designated type.

I objected to this aspect of Michiharu's proposal on other
grounds, however: they are referring to two different things.
See my first response in Michiharu's "Comment on hierarchical
Resource" thread for more on this.
