Schema - regular expression question

[Benson Cheng]

Hi All,

I have a regular expression qeustion in Xerces 1.4.3, in the following piece
of the schema I want define the "Quantity" element as a double but only
allow 1 to 10 digits.  But for some reason the parser does not throw an
error for the value of "100000000000000", does anyone know how should I
define this kind of the schema.

<xsd:element    name="Quantity">
        <xsd:simpleType>
                <xsd:restriction base="xsd:double">
                        <xsd:pattern value="\d{1,10}"/>
                </xsd:restriction>
        </xsd:simpleType>
</xsd:element>

Thanks,
Benson.
