The XProc spec does not specify that the steps must be executed in  
document order. The only constraint comes from port connections, where  
a step A depending on the output of step B requires that A should be  
executed before B.

p:store can pretty well be declared in the middle of your document,  
you just have to declare an explicit p:pipe connection for the  
following step.

For instance:

<my:step-a name="stepA" />

<p:store/>

<my:step-b>
	<p:input port="source">
		<p:pipe step="stepA" port="result"/>
	</p:input>
</my:step-b>

See my answer above: in this case you cannot rely on automatic  
connection.
