You can use <bind ref=".." calculate="..."/> if there is a programmatic
relationship you can express between the <message> and the <author> elements
that doesn't violate the dynamic predicates rule.  (As expressed in your
fragment below, it's not clear what the relationship is; is it XPath
following-sibling, or are the two elements in different parts of the
document?)

See

e

I'll re-write your markup to make it an easier example for me (and omit
namespaces).  I believe something like the following will work, bit I
haven't run it through a test:

<model>
 <instance>
  <bboard>
   <threads>
    <thread>
     <author>I am</author>
       <message>
        <author>I am</author>
      </message>
    </thread>
   </threads>
  </bboard>
 </instance>

 <bind nodeset="/bboard/threads/thread/message/author"
calculate="../../author"/>
</model>

If the relationship is between message and threads is different, you will
have to use different markup, but bear in mind the dynamic predicates rule
(see spec).

Hello!

Suppose I have a form input element and want it to be in two different
places in the instance, for example I want

<thread>
  <author>I am</author>
</thread>
<message>
    <author>I am</author>
</message>,

for the author being inserted from only one input. Is it possible anyway?
