what is the advantage of this strategy? I think we still have to rely on
datatype library to test the equality of two types.


To get ride of anonymous types, I think we should rather allow
user-defined types.

For example, usually key and keyref has the same type. As long as we
have @key and @keyref attached to <data/>, we can't reuse the same
<data/> definition from multiple locations.

The "ID/IDREF strawman #1" allows this:

<key>
  <ref name="myLocalTimeType"/>
</key>

<keyref>
  <ref name="myLocalTimeType"/>
</keyref>
