[XSCD] Last Call WD Comments

Hi,
i read the Document ( http://www.w3.org/TR/2005/WD-xmlschema-ref-20050329/ ) 
with big interest and great confusion. here, some of my questions and 
comments:

general:
- XPath is a non-normative reference. this means, the steps defined in the 
WD are not an "extension to XPath (1.0)"? but will be implemented and 
resolved by XPath-processors, because you are using the same syntax? XMLNS 
ist not mentioned in the references-list.

- as i understood it: not (directly) accessible are
    namespaces other than targetNS
    the baseURI of the schema-as-a-whole schema component (uh?)
    particles (4.2.12)
    attribute use (4.2.14)
    abstract element declarations

- 4.1 / first list (or 2nd list):
wildcards are / wildcard is not mentioned (see 4.2.13)

Gruss
