Thanks Hans, It's good to know the --result problem is not a bug, but
a feature. My problem then arises from my use of \note as opposed to
\footnote. In processing a <ref> tag in the xml, I need to test if the
current ref node has an ancestor <div> with attribute:
@xml:id='apr_engl'. If it does, I need to create a \footnote whose
text comes from a <note> element with attribute xml:id='N020-18', if
it does not, I need to create a \note whose reference number
corresponds to the one created by \footnote and thus points to the
same footnote contents:

<div xml:id='apr_arab'>
    <...>
        <ref target="#N020-18">referenced text</ref>
    <...>
</div>
<div xml:id='apr_engl'>
    <...>
        <ref target="#N020-18">referenced text</ref>
    <...>
</div>
...
<note xml:id='N020-18'>footnote contents</note>

To result in:

arabic text (1)
english text (1)
(1) footnote content

Currently I'm getting:

arabic text ??
english text (1)
(1) footnote content

Document order problem maybe?

thanks,
Jon
