Diffs between Part 1 and envelope schema

OK, I've swept Part 1[1] and the envelope schema[2]. Here are the diffs
as I see them:


1.	The spec[1] says of SOAP Header "Zero or more namespace
qualified element information items in its [children] property.", making
no statement about the allowable namespaces on those children.
	The schema says <xs:any namespace="##other"
processContents="lax" minOccurs="0" maxOccurs="unbounded"  />,
constraining the namespaces of the children to be something other than
http://www.w3.org/2002/12/soap-envelope

2.	The spec[4] lists a relay attribute.
	The schema is missing this attribute.

3.	The spec[5] says of xml:lang on Text elements: "Each child Text
element information item SHOULD have a different value for its xml:lang
attribute information item.", which allows for a given xml:lang value to
be duplicated.
	The schema says 

	  <xs:element name="Text" type="tns:reasontext" minOccurs="1"
maxOccurs="unbounded" >
	    <xs:unique name="xmllang">
	      <xs:selector xpath="." />
	      <xs:field xpath="@xml:lang" />
	    </xs:unique>
	  </xs:element>

	which enforces that xml:lang be unique across Text elements.

I've fixed item 2 in my local copy.
