I'm trying to create a simpleType definition for length, which is 
defined as a real number plus a unit qualification. I've come up with 
this, which I know is wrong.

    <simpleType name = "length_Type">
        <restriction base = "NMTOKEN">
            <pattern value = "[+-]?\d+\.?\d*[p|m|i|c|e][x|t|m|n]"/>

The unit qualification is one of px, pt, mm, in, cm, em  so I 
constructed the above 2 part choice. The problem being it allows illegal 
values such as ix. How do I create a list of atoms greater than one 
character? [px|pt|mm|cm|in|em] is not right.
