Re: p:namespaces on p:variable?

Interesting question

The key point is here
[[
If the select attribute was used to specify the value and it consisted of a
single VariableReference (per [XPath 1.0 <#xpath>] or [XPath 2.0 <#xpath2>],
as appropriate), then the namespace bindings from the referenced option or
variable are used.
]]

It looks like it means that

[[

<p:pipeline type="ex:delete-in-div"
            version="1.0"
            xmlns:p="http://www.w3.org/ns/xproc"
            xmlns:ex="http://example.org/ns/ex"
            xmlns:h="http://www.w3.org/1999/xhtml">
<p:option name="divchild" required="true"/>


<p:delete>
  <p:with-option name="match" select="concat('h:div/',$divchild)">
    <p:namespaces xmlns:html="http://www.w3.org/1999/xhtml"/>
  </p:with-option>
</p:delete>

</p:pipeline>

]]

is equivalent to
[[

<p:pipeline type="ex:delete-in-div"
            version="1.0"
            xmlns:p="http://www.w3.org/ns/xproc"
            xmlns:ex="http://example.org/ns/ex"
            xmlns:h="http://www.w3.org/1999/xhtml">
<p:option name="divchild" required="true"/>

<p:variable name="match" select="concat('h:div/',$divchild)">

   <p:namespaces xmlns:html="http://www.w3.org/1999/xhtml"/>

</p:variable>


<p:delete>
  <p:with-option name="match" select="$match"/>
</p:delete>

</p:pipeline>

]]

Of course it's the dummy example, but am I right here ?
