Problem in Retrieving Part 2 Recommendation

I have problem getting the whole Part 2 Recommendation.  For example, using this URL http://www.w3.org/TR/xmlschema-2/built-in-datatypes I could not get the diagram for datatypes.  Evidently the document retrieved only has contents up to section 2.5.1.3.

Please fix the problem so we can read the entire document.

Thanks,

Scott Tsao
