OK, you asked for it :)

[66]    CharRef ::=  '&#' [0-9]+ ';' | '&#x' [0-9a-fA-F]+ ';'

and, as stated in the xml spec:

If the character reference begins with "&#x", the digits and
letters up to the terminating ; provide a hexadecimal representation
of the character's code point in ISO/IEC 10646. If it begins just with "&#",
the digits up to the terminating ; provide a decimal representation
of the character's code point.

so "&#045;" == "&#45;" == "&#x2D;"

Viele Grüße,
