Yep, I'd played around with that
and it solved the problem. However, as I posted on the W3C list to HT's
answer, it leaves a very clear inconsistency:
What list did HT answer to? I find this problem with restriction a bit
strange and I'd like to follow up on the information but I haven't seen
a answer from HT on the list. Can you please point me to that reply?
If I try restricting the following:
<xsd:complexType name="Items">
<xsd:sequence>
<xsd:element name="item" minOccurs="0"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="productName"
type="xsd:string"/>
<xsd:element name="quantity">
<xsd:simpleType>
<xsd:restriction
base="xsd:positiveInteger">
<xsd:maxExclusive
value="100"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="USPrice"
type="xsd:decimal"/>
<xsd:element name="shipDate"
type="xsd:date" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
<xsd:attribute name="shipBy">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="air"/>
<xsd:enumeration value="land"/>
<xsd:enumeration value="any"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:attribute>
</xsd:complexType>
the restriction of the anonymous simple type for the element
"quantity" is acceptable, but the restriction of the anonymous simple type
for the attribute "shipBy" is not. Maybe this is just a misinterpretation
in Xerces, but if it is intended to be allowed then what is the rationale
for treating anonymous types of elements differently from anonymous types
of attributes?
This seems very strange indeed. However, in your previous example I tried
to get rid of the anonymous simple type
<xsd:simpleType name="upto100integer">
<xsd:restriction base="positiveInteger">
<xsd:maxExclusive value="100"/>
</xsd:restriction>
</xsd:simpleType>
but I still got the same error from the Schema Quality Checker.
