Hi,
The XML Schema for XHTML 1.0 transitional  
[http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd ] is apparently  
not allowing
the "name" attribute for the "form" element, as I think it should.

Here is the reference about this attribute in the HTML 4.01 specification.
[http://www.w3.org/TR/html401/interact/forms.html#adef-name-FORM ]

I suggest an update of this schema, line 2118. Here is  
xhtml1-transitional.xsd, lines 2097-2122:

<xs:element name="form">
  <xs:complexType mixed="true">
   <xs:complexContent>
    <xs:extension base="form.content">
     <xs:attributeGroup ref="attrs"/>
     <xs:attribute name="action" use="required" type="URI"/>
     <xs:attribute name="method" default="get">
      <xs:simpleType>
       <xs:restriction base="xs:token">
        <xs:enumeration value="get"/>
        <xs:enumeration value="post"/>
       </xs:restriction>
      </xs:simpleType>
     </xs:attribute>
     <xs:attribute name="enctype" type="ContentType"
       default="application/x-www-form-urlencoded"/>
     <xs:attribute name="onsubmit" type="Script"/>
     <xs:attribute name="onreset" type="Script"/>
     <xs:attribute name="accept" type="ContentTypes"/>
     <xs:attribute name="accept-charset" type="Charsets"/>
     <xs:attribute name="target" type="FrameTarget"/>
     <xs:attribute name="name" type="xs:NMTOKEN"/><!-- Line added -->
    </xs:extension>
   </xs:complexContent>
  </xs:complexType>
</xs:element>


This "name" attribute for the "form" element is correctly declared in the  
DTD
[http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ] on line 889.

Here is an extract from xhtml1-transitional.dtd, lines 885-896:

<!ATTLIST form
  %attrs;
  action      %URI;          #REQUIRED
  method      (get|post)     "get"
  name        NMTOKEN        #IMPLIED
  enctype     %ContentType;  "application/x-www-form-urlencoded"
  onsubmit    %Script;       #IMPLIED
  onreset     %Script;       #IMPLIED
  accept      %ContentTypes; #IMPLIED
  accept-charset %Charsets;  #IMPLIED
  target      %FrameTarget;  #IMPLIED

Cordially,
