"Used by" not correctly populated during ODD to HTML5 processing

[lb42]

The "Used by" field of a Datatype specification does not include relevant attributes which are inherited from an attribute class, though it does include locally defined attributes, and dataspecs.

This should be easy to fix since it only happens for HTML generated from an ODD but works fine in the Guidelines.

For an example, try generating HTML from tei_simple.odd and look at e.g. the spec for teidata.probCert. This is used by @cert, which is included in the schema via its membership in att.global, but does not appear in the "used by" block.

@ebeshero and I confirmed this as of today.
