Should I also understand that DTDs are not fully convertible to XML schemas?
Here's an excerpt of a DTD:
<!ELEMENT ... ((KIT? , STOCKS) | (STOCKS+ , PRICE , ...))
and here is an excerpt of the XSD generated with oXygen (I found it in your
signature)
<xs:choice>
<xs:sequence>
<xs:element minOccurs="0" ref="KIT"/>
<xs:element ref="STOCKS"/>
</xs:sequence>
<xs:sequence>
<xs:element maxOccurs="unbounded" ref="STOCKS"/>
....
</xs:sequence>
</xs:choice>
As you can see, it is almost the same situation as above. Or is it that the
DTD is not valid? oXygen says it is valid, and I have no further knowledge
on this issue. As a regular expression it is very valid (at least imo)

Cipi
