there are:
flag x +
flag r +

the output produced by r + is somewhat strange, but may be good enough. In =
your case, it shows difference between *$a* and *$a^*:

the former is:

Xdol (a*) () ()
Xmark () ()
Xword () () ()
Xconc (*) () ()
rc: null list in concatenation


(guess `Xdol (a*)' means `dereference variable a*' (preasumably empty), whi=
ch is  in turn Xconc()atenated with literal `*' and thus the error)

the later is=20

Xdol (a) () () (*) ()
Xmark (name) () (*) ()
Xword () (name) () (*) ()
Xconc (*) (name) () (*) ()
Xconc (*name) (*) ()

an XML parser will recognize that the document is stored in the traditional=
