Re: Adding p:group gets rid of ERR : Unbound primary output.. why?

Good call Vojtech,, I added a name to the save-output step and the error
message is related to that step. I hadn't noticed that I was thinking the
step-name was the name I suppose.

E [Calabash XProc] ERR : Unbound primary output: [output result on SAVEME]

   <oh:save-output name="SAVEME"
step-name="saveidentifyDifferentOldNewOfficeCodes">
      <p:with-option name="save" select="'true'"/>
      <p:with-option name="href"
select="$hrefIdentifyDifferentOldNewOfficeCodes"/>
    </oh:save-output>
