It probably predates inclusion of use cases in the use cases and
requirements document, but there's:

   R12 The serialization part carrying the start of the primary
       envelope document element must be easily
       locatable/identifiable.

which points more towards providing the "Start" parameter than towards
fixing the order of parts.

Note that there used to be an R11 too:

<!--
<gitem id="r11"><label>R11</dt>

	<p>The serialization should not specify a particular physical
ordering of parts.</p>
	 <p>In particular, this requirement was motivated by a use
case in which
the primary (SOAP) part was not required to be the first part.</p>
    <p>Physical order is significant, and there are cases in which
control
over physical order is important (for example, see R26).  The issue
here is whether the serialization should be as rigid as SwA in
insisting, for example, that the primary SOAP part be the first
part.</p>
