Gerard,
I understand. Strictly as per the XForms spec, this is not possible: the
value of the @control attribute has to be statically determined. This is
a case where Attribute Value Templates (AVTs) would be handy, i.e. you
could write things like:
<xforms:setfocus control="my-control-{instance('foo')/bar}"/>
Discussions about AVTs have been going on in the XForms Working Group,
but we know that those won't be in XForms 1.1. However some
implementations use them already. In particular we already support them
in places like xforms:submission.
Supporting AVTs on xforms:setvalue would actually be fairly easy for us
to implement.
Another solution, without AVTs, and if you don't have many controls to
set focus to, is to use conditional actions:
<xforms:setfocus if="condition-1" control="my-control-foo"/>
<xforms:setfocus if="condition-2" control="my-control-bar"/>
etc.
