PEX14 says:

"ERH asks "what should I do if the encoding attribute
does not satisfy [XML 1.0's EncName] production [81]"

The (admittedly non-normative) schema fragment in section 3 defines it as:

   <xs:attribute name="encoding" use="optional" type="xs:string"/>

This seems to indicate that we didn't want non-conformance to production 
[81] to always produce an error.

But it can make sense to check the syntax if the attribute is actually 
used.  It is used only when parse="text", and then only if the first two 
items (external info, media type says some kind of XML) in the list of 
steps to determine the encoding are not available.

We already cover the case of an unsupported encoding (resource error). 
But we could distinguish the case where the att value does not meet 
production [81], making it a fatal error.  This would make sense since 
it is not the resource itself that has an error, it is the XInclude 
instruction and this would not be fixed by trying later or with another
