According to section 9.5.6, "the SimpleValue element is used for
primitive values, enum values and object references. Its value
attribute contains a stringified representation of the primitive

It goes on, "for char, wchar, string, wstring types, the value
attribute holds an unquoted literal (i.e. no single or double

and no leading L prefix) that conforms to the IDL syntax and
semantics chapter.
