Sorry, you're both on the wrong track.

Given this pair of elements in an XML Schema document:

<xsd:complexType name="varies">
 <xsd:complexContent>
   <xsd:extension base="xsd:anyType"/>
  </xsd:complexContent>
 </xsd:complexType>

  <xsd:complexType name="myType">
   <xsd:complexContent>
      <xsd:extension base="varies">
        <xsd:attribute name="foo" type="xsd:int"/>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>

the complex type definition assigned to 'myType' has, effectively, the
following representation:

 <xs:complexType name="myType">
  <xs:sequence>
   <xs:any minOccurs="0" maxOccurs="unbounded" processContents="lax"/>
  </xs:sequence>
  <xs:attribute name="foo" type="xs:int"/>
  <xs:anyAttribute processContents="lax"/>
 </xs:complexType>

It follows that 

 <myElement anotherAttribute="x" foo="y">bar</myElement>

is _not_ valid wrt 'myType', because 'y' is not a valid *int*.
