Well, as the mapping from document character set to system character
set is not specified in SGML, and hence, is system dependent, I think
most current practices, even numeric character references, are legal
with a document character set of ISO 10646.
No, numeric character references *are* broken if they are used in
reference to the system character set rather than the document character
set. The standard is quite clear on this.
