If numeric character references (with the same apparent syntax as XML's
numeric character references) were introduced, they would hide completely
XML's numeric character references. As a consequence, XML numeric
character references would need to be encoded as
& & ; # n n n ;
rather than as
& # n n n ;
in order to be visible to an XML processor.
Consider, for example,
<el att="abc&" />
This is not well-formed if & is a character reference at the encoding
level. It represents exactly the same Unicode character sequence as
<el att="abc&" />
does.
Therefore either a different syntax must be specified for the encoding-level
numeric character references, or the above must be encoded as:
<el att="abc&&;#x26;" />
