Hello,
I would like to use Xform to edit the following element :
<dcterms:spatial xsi:type="dcterms:Point">east=456; 
north=123;</dcterms:spatial>

I could use :
<xf:input ref="dcterms:spatial[@xsi:type='dcterms:Point']" 
class="dcterms:spatial">
     <xf:label>Latitude / Longitude:</xf:label>
</xf:input>

But is there a way to display two inputs to let the user enter the east 
value and the north value separately ?

Thanks,

--
