Validation of XSD (minLength, maxLength and pattern)

[jbossws_newbee]

I have a WSDL operation which is based on a XML schema with the following info:

<xs:element name="CheckInDate">
<xs:annotation>
<xs:documentation>CheckInDate: YYMMDD</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:length value="6"/>
<xs:pattern value="\d\d\d\d\d\d"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

<xs:element name="FolioID">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:minLength value="0"/>
<xs:maxLength value="25"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

Couple of questions around this schema:
1. Does JBossWS framework understand the xml schema constraints of xs:minLength, xs:maxLength and xs:pattern, if specified?

2. What kind of error (Soap or otherwise) does the JBossWS framework throw or report to the WS-Client, if minLength, maxLength and pattern constraints are violated.?

3. If not, do I need to do a validation around these constraints in my code and throw a wsdl 'validation error' fault.

Thanks in Advance!
