is not valid, as can easiy be confirmed with a validating xml parser.

On the question of whether to use csymbol or ci they are both allowed in
exactly the same paces. ci is intended to encode a fairly generic
identifier, at one extreme, general variable expressions such as f(x)
wich you would use ci to encode both f and x. csymbol can be used to
indicate that the identifier denotes a symbol with a particuar fixed
meaning specified externally, however the mathematial distinction
between what is a fixed meaning and what is variable, is rather vague,
depending on context that often s not explicit.
