Chuck,
I don't think you can define a simpleType for length as real plus a unit
qualification. Because,
Simple Type definitions provide for:
Establishing the ·value space· and ·lexical space· of a datatype,
through the combined set of ·constraining facet·s specified in the
definition;
Attaching a unique name (actually a QName) to the ·value space· and ·
lexical space·.
Cheers
Bibhakar Saran

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]"/>
</restriction>
</simpleType>
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.
Chuck
