That's non-deterministic too. It's the equivalent of
> <xsd:complexType name="timeframeType">
> <xsd:choice>
> <xsd:sequence>
> <xsd:element ref="earliestdate"/>
> <xsd:element ref="latestdate"/>
> </xsd:sequence>
> <xsd:choice>
> <xsd:element ref="earliestdate"/>
> <xsd:element ref="latestdate"/>
> </xsd:choice>
> </xsd:choice>
> </xs:complexType>
If the parser encounters earliestdate it does not know which branch of
the content model to use.
