How about this then. I think the schema is valid, but I didn't try to
validate it. It allows for a choice strictly between
<li><p>...</p></li> and <li>...</li>.
<xs:complexType name="liWithPOrNoP">
<xs:choice>
<xs:sequence>
<xs:element name="li">
<xs:complexType>
<xs:sequence>
<xs:element name="p" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:element name="li" type="xs:string"/>
</xs:choice>
</xs:complexType>
