local schema for listitem

[Chad Berkley]

Hi Tim,

I'm not sure I completely understand your problem, but here's a shot...I
think what you want to do is allow a choice between a paragraph and
something else right?  If so, would this work for you?

<xs:complexType name="pOrAny">
  <xs:choice>
    <xs:element name="p" type="xs:string"/>
    <xs:any processContents="lax"/>
  </xs:choice>
</xs:complexType>

the problem with using an xs:any is that then any additional tagging is
valid as well.  I'm not sure if that's what you want.  

if I'm totally off the mark here, clue me in and maybe i can figure
something else out.
