XSD Sequence with optional elements and any

Question

Is it possible to define a complex type sequence with optional elements followed by n optional any elements? Currently I have this XSD which violaets UPA:

<xs:complexType name="itemtype">
    <xs:sequence>
        <xs:element name="uuid" type="uuidtype"/>
        <xs:element name="lastname" type="nametype"/>
        <xs:element name="isActive" minOccurs="0" type="isactivetype"/>
        <xs:element name="countries_scope" type="countryscopetype"/>
        <xs:element name="origin" minOccurs="0" type="nametype"/>
        <xs:element name="url" minOccurs="0" type="nametype"/>
        <xs:element name="email" minOccurs="0" type="emailtype"/>
        <xs:element name="description" minOccurs="0" type="nametype"/>
        <xs:element name="town" minOccurs="0" type="nametype"/>
        <xs:element name="role" minOccurs="0" type="nametype"/>
        <xs:element name="source" minOccurs="0" type="nametype"/>
        <xs:element name="origin_zip" minOccurs="0" type="nametype"/>
        <xs:element name="town_zip" minOccurs="0" type="nametype"/>
        <xs:any minOccurs="0" maxOccurs="unbounded" processContents="lax"/>
    </xs:sequence>
</xs:complexType>

A possible XML could be:

<item>
  <uuid>1</uuid>
  <lastname>Yanick</lastname>
  <country_scope>CHE</country_scope>
  <role>Student</role>
  <age>24</age>
</item>

Here only the optional role is used and age would be one any element.

The solution is simple. THe last element bevore the any can't be an optional. This XSD would work:

<xs:complexType name="itemtype">
<xs:sequence>
    <xs:element name="uuid" type="uuidtype"/>
    <xs:element name="lastname" type="nametype"/>
    <xs:element name="isActive" minOccurs="0" type="isactivetype"/>
    <xs:element name="origin" minOccurs="0" type="nametype"/>
    <xs:element name="url" minOccurs="0" type="nametype"/>
    <xs:element name="email" minOccurs="0" type="emailtype"/>
    <xs:element name="description" minOccurs="0" type="nametype"/>
    <xs:element name="town" minOccurs="0" type="nametype"/>
    <xs:element name="role" minOccurs="0" type="nametype"/>
    <xs:element name="source" minOccurs="0" type="nametype"/>
    <xs:element name="origin_zip" minOccurs="0" type="nametype"/>
    <xs:element name="town_zip" minOccurs="0" type="nametype"/>
    <xs:element name="countries_scope" type="countryscopetype"/>
    <xs:any minOccurs="0" maxOccurs="unbounded" processContents="lax"/>
</xs:sequence>
