Schema validation

[James Bates <ja...@amplexor.com>]

Considering this piece of schema:

<xs:complexType name="seqType">
    <xs:sequence>
        <xs:sequence minOccurs="2" maxOccurs="3">
            <xs:element ref="A" minOccurs="3" maxOccurs="5" />
        </xs:sequence>
   </xs:sequence>
</xs:complexType>

I would expect an instance such as:

<root xsi:type="seqType">
    <A/>
    <A/>
    ....
</root>

to validate only if the number of A's can be expressed as a product of 2 or 3 
with 3, 4 or 5, i.e. 6,8,9,10,12 or 15 A's.  If there were 7,11,13 or 14 A's, 
then the instance shouldn't validate. This is my understanding from several 
readings of paragraphs 3.8.4 and 3.9.4 part 3) of the XMLSchema 
specification, part 1.

Using Xerces 2.2.0, it would however appear to validate any number of A's
between 6 and 15. (MSXML4 demonstrates identical behaviour btw)
That's even with the 
"http://apache.org/xml/features/validation/schema-full-checking" feature 
turned on. Is this a (known) bug? Or am I misreading the XML Schema's spec?

Thanks,
James

As far as can understand paragraphs 3.8.4 and 3.9.4 part 3) of the XMLSchema 
specification, part 1, this is wrong, .
