Sorry David,
This is still non-deterministic because when the parser encounters a
description element, it does not know which branch of the content model
to take. I think what you want is:
> <xs:complexType name="timeframeType">
<xs:sequence>
<xs:element ref="description" minOccurs="0"/>
> <xs:choice>
> <xs:sequence>
> <xs:element ref="earliestdate"/>
> <xs:element ref="latestdate" minOccurs="0"/>
> </xs:sequence>
> <xs:element ref="latestdate"/>
> </xs:choice>
</xs:sequence>
> </xs:complexType>
Hope that helps,
Priscilla
