using xforms:output in xforms:label

<xforms:group ref="instance('criteria-instance')/filters/filter[1]" id="criteria-context-section1-row1-col1">
   <xforms:input ref="special-display/display-value" id="profitCenterPath-section1-row1-col1">
      <xforms:label model="resources-model">
         <xforms:output model="resources-model" ref="instance('grouping-resources')/filters/label[@name = xxforms:context('criteria-context-section1-row1-col1')/@name]"/>
      </xforms:label>
   </xforms:input>
</xforms:group>

But it appears the xxforms:context is not able to find the enclosed xforms:group, if I use @ref on the label it works fine, but I wanted to add ': ' to the end of all the labels without having to store it

Any ideas?

Thanks
