Jeni,

What you suggest here seems quite elegant to me. It is at the same
time simple and powerful. So putting some of those things together,
let's consider an example:

<p:pipeline xmlns:p="http://www.w3.org/2006/XProc/Pipeline">
	
	<p:input name="request"/>
	<p:output name="response" select="$result"/>

	<p:variable name="has-namespaces"
		select="count(/*/namespace::*) > 0"/>
	
	<p:step name="validate">
		<p:with-input name="schema" href="my-schema.xsd"/>
		<p:with-input name="document" select="$request"/>
		<p:with-param name="do-namespace-processing"
			select="$has-namespaces"/>
		<p:with-output name="name" label="validity"/>
	</p:step>

	<p:choose>
		<p:when test="$validity = 'true'">
			<p:step name="process-request">
				<p:with-input name="document" select="$request"/>
				<p:with-output name="result" label="result"/>
			</p:step>
		</p:when>
		<p:otherwise>
			<p:step name="return-error">
				<p:with-output name="error" label="result"/>
			</p:step>
		</p:otherwise>
	</p:choose>
	
</p:pipeline>

Are we on the same line?
