RDF Literal datatypes from a PSVI

Can one get typed literals by applying an XML Schema:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <xsd:annotation>
    <xsd:documentation xml:lang="en">XML Schema for RDF Address Records
    </xsd:documentation>
  </xsd:annotation>

  <xsd:element name="Address" type="AddressType"/>

  <xsd:complexType name="AddressType">
    <xsd:sequence>
      <xsd:element name="street"   type="xsd:string"/>
      <xsd:element name="city"     type="xsd:string"/>
      <xsd:element name="province" type="xsd:string"/>
      <xsd:element name="postCode" type="xsd:decimal"/>
    </xsd:sequence>
  </xsd:complexType>

</xsd:schema>

to RDF/XML instance data:

<rdf:RDF xmlns:rdf="@@@">
<Address xmlns="@@@">
  <street>some street</street>
  <city>some city</city>
  <province>some province</province>
  <postalCode>some postalCode</postalCode>
</xsd:schema>
</rdf:RDF>

before parsing it? (Apart from implementations, is the parser allowed
to use the type annotations in the PSVI?
