Strange BPEL behaviour - no mismatch detected

Question

Hi.
I am facing to this problem.
I define
     <element name="msgPushRequest">
          <complexType>
               <sequence>
                    <element name="name" type="string"/>
                    <element name="type" type="string"/>
                    <element name="date" type="date"/>
                    <element name="price" type="decimal"/>
               </sequence>
          </complexType>
     </element>
used in input message
     <message name="msgPushRequestMessage">
          <part name="payload" element="client:msgPushRequest"/>
     </message>
I send to process message like this
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:prep="http://xmlns.oracle.com/msg">
<soapenv:Body>
<prep:msgPushRequest>
<prep:name>Fru</prep:name>
<prep:type>new</prep:type>
<prep:price>ooo</prep:price>
<prep:date>www</prep:date>
</prep:msgPushRequest>
</soapenv:Body>
</soapenv:Envelope>
Process get message and have no problem with date value = "www" and decimal = "ooo".
What is it?
Even have no trouble with assign this values to variable xsd:date and xsd:decimal type.
Thanks for you aid

Thanks, it works.
But when I assign in process
Assign_tests
[2007/07/18 07:44:45] Updated variable "testString"less
<testString>Fru</testString>
[2007/07/18 07:44:45] Updated variable "testString"less
<testString>new</testString>
[2007/07/18 07:44:45] Updated variable "testDecimal"less
<testDecimal>2007-12-01</testDecimal>
[2007/07/18 07:44:45] Updated variable "testDate"less
<testDate>1</testDate>
compiler show warning about mismatched assign (incompatible types) but when process run error isn't raised.
