>§220.127.116.11, “ST_Xstring (Escaped String)” says:
>For all characters that cannot be represented in XML as defined by the
>XML 1.0 specification, the characters are escaped using the Unicode
>numerical character representation escape character format _xHHHH_, where H
>represents a hexadecimal character in the character's value.

W3C XML clearly defines which character is legal. We should
mention *Well-formedness constraint: Legal Character.*
Or, does this DR ask how we can represent a literal such as "_x2345"?
