In general I don't think W3C XML Schema can satisfy your requirements but believe that there may be a work around for specific cases. Your example wasn't detailed enough to tell if your case is one where a work around is possible. Perhaps some sample XML or schema fragment?

sure that there is no way to represent in XML Schema that "at least one of
the following X elements must appear in the XML document" - **am I
correct?**
How about:
<xsd:any minOccurs="0" maxOccurs="unbounded" > <!-- or 1 -->
<!-- nest xsd:sequence or xsd:choice here -->
</xsd:any>
