Noel -
I do not believe that generateDS.py will support restrictions on a
simpleType. I just recently did some work to add some support for
restrictions on a complexType.
I'd recommend that you change it to something like the following:
<xs:element name="AHLeakSA" type="xs:double" minOccurs="0">
<xs:annotation>
<xs:documentation>Fraction of air-handler flow rate that is
lost on the supply-side of the air-handler.</xs:documentation>
</xs:annotation>
</xs:element>
That's about the best that generateDS.py can do right now, I'm
afraid. Will that work for you. I'll give it a test myself, tomorrow.
And, I'll take another look to see if there is a simple fix for this.
