comments re Sstc-saml-metadata-algsupport-csprd02

These comments pertain to Sstc-saml-metadata-algsupport-csprd02 (PDF).

- The document contains no line numbers and is therefore difficult to
reference. This is probably enough to require an additional public
review.

- The second paragraph of section 2.4 refers to extension elements to
be included as child elements in an <md:EntityDescriptor> element
and/or an element whose type is based on md:RoleDescriptorType, but
the interpretation of *multiple* such elements is deferred to section
2.5. Although the producer can infer its conformance requirements from
the text in section 2.5, I think the producer's requirements should be
explicitly stated in section 2.4.

- In the schema listed in section 2.4, no extended XML attributes are
allowed. Is this intentional?

Thanks,
