RE: [xml-dev] Where does the XML specification discuss the character sequence '>' followed by the combining long solidus character (U+0308)?

The start tag production indicates unambiguously that the markup end 
is detected at the right angle bracket:

    http://www.w3.org/TR/2008/REC-xml-20081126/#NT-STag
    [40] STag ::= '<' Name (S Attribute)* S? '>'

... which would leave subsequent characters as data.

The only reference to NFC is in a non-normative annex and is related 
to the suggested practice of expressing names of elements.

The specification is very explicit about what characters *in the 
stream* form markup and, therefore, which are not markup.  The spec 
says nothing about processing the Unicode characters before doing 
markup detection ... why does it have to explicitly say it doesn't apply?

As I said ... I perceive normalization to be an application 
processing task and not an XML processor's parsing task.  The spec 
states which code-points are markup.
