olink to a document only

Hello,

Is there a way to create an olink to a document but *not* to a specific
part of it.
I would like to write something like:
<olink targetdoc="idref">See reference doc</olink>
So I would get:
<a href="../refdocs/ref.html">See reference doc</a>

I do not want to point to a specific anchor into the document. But not
setting the targetptr attribute (or setting it to an empty string) leads
to errors.

Any idea ?
