Creating elements

Hi all,

I was just wondering what is the most straightforward way to create an
element whose name is generated dynamically. The simplest solution I
managed to come up with is this:

<p:rename>
  <p:input port="source">
    <p:inline><foo/></p:inline>
  </p:input>
  <p:with-option name="new-value" select="..."/>
</p:rename>

To me, this seems both elegant ("Nice, I can use p:rename for that") and
confusing at the same time ("Why do I have to use p:rename for
*creating* content!?")...

What is your opinion on this? Is it OK, or should the spec provide some
functionality specifically for these types of use cases (by adding a new
step, or by extending the functionality of the existing steps, ...)?
