computed ports and viewports

Are we going to allow:

<p:viewport name="v" match="/doc/section">
<p:viewport-source>
   <p:pipe step="other" port="result" select="/section/section"/>
</p:viewport-source>
...
</p:viewport>

?

It seems like this is OK.

inflexions, i.e. to the degree of analysis effected by the language
considered."
