You have a contradiction there: you are requiring two different
behaviours in the presence of sect1 ... the first case it allows the
others, and the second case it does not.
To proceed, I'll assume that you did not mean for sect1 to be allowed
in the first case:
<xs:complexType name="chapterType">
<xs:sequence>
<xs:element name="title"/>
<xs:choice>
<!--the author- and para-element can occur unboundedly
and the subtitle-element can occur only once-->
<xs:sequence>
<xs:element name="subtitle"/>
<xs:choice maxOccurs="unbounded">
<xs:element name="author"/>
<xs:element name="para"/>
</xs:choice>
</xs:sequence>
<!--if an sect1-element occurs the para-, author- or
subtitle-element should not occur-->
<xs:element name="sect1"/>
</xs:choice>
</xs:sequence>
</xs:complexType>
I hope this helps.
