Can you leverage a union? The following defines a 'money' type that can
also be empty:

<xsd:simpleType name="MyMoneyType">
      <xsd:restriction base="xsd:decimal">
        <xsd:fractionDigits value="2"/>
      <xsd:restriction base="xsd:token">
        <xsd:enumeration value=""/>

ok, so it is valid legal as it stands.

my question is: is there a way to write the schema or use a later verson
xml or xmlschema in such a way as to ignore this white space or consider
not to be an element. i can probably hack it with code by seeing if it 
contains no non-space characters, but it would be nice if jdom would not

consider this to be a text element.

i don't mind the white space. i just don't want to "see" it as an
