Roger,

Apologies for this reply being very, very late. 

You obviously did not cite all "XML technologies" (e.g., XQuery
isn't mentioned), but that would be difficult at best anyway. 

Some omissions from even the last version of your list:

* In XPath 3, URI qualified names
 

URIQualifiedName    ::=   

URILiteral ":"

NCName 

* In XPath 2 and beyond, collations
   ("collation"

URILiteral)

* In XPath 2 and beyond, the document-uri() function returns a
URI

* In XPath 2 and beyond, the uri-collection() function returns a sequence
of URIs

* In XPath 2 and beyond, the namespace-uri() function returns a
URI

* In XPath 2 and beyond, the namespace-uri-for-prefix() function returns
a URI

* In XPath 2 and beyond, the namespace-uri-from-QName() function returns
a URI

* In XPath 3, the unparsed-text() function accepts a URI
argument

* In XQuery 3 (in case you want to include this language), URIs are used
in several places within query prologs:
  - namespace declarations, including module namespace declarations
and default namespace declarations
  - option declarations (e.g., serialization options
"output" and "parameter-document")
  - default collation declarations
  - base URI declarations
  - schema import declarations
  - module import declarations

* In XQuery 3 (in case you want to include this language), URIs are used
in constructors of various sorts

Hope this helps,
   Jim
