Sorry, there are no composite types in XML Schemas.  Your choices are
either:

   *  a token, using a regular expression
   * a list of legnth 2 of the union of a currency enumeration and a
double--but in this
case you must use space separator between the $ (or the Rs) and the number.

XML Schemas 1.0 excluded support for composite data types (notations, which
need
"microparsing") or localized lexical forms.  It wants elements and
attributes to be
used to delimit different parts of data.

The more that people say "this is unacceptable", the greater the chances
that it may
be dealt with in XML Schemas 1.1, and not in XML Schemas 2.0, I suppose.  In
my
view, it is a serious ommission that means that XML Schemas, in effect,
requires a smart front end to convert from human-friendly notations for
currency (and dates) into
space-delimited tokenized forms.
