FW: [xquery-talk] optional attributes via function?

[Dmitri.Colebatch at toyota.com.au]

Per,

having a little trouble with this....

> element widgetspecification {
>    attribute validFrom myfn:transformDate($spec/VALIDFROM),
>    myfn:outputValidToIfRequired($spec/VALIDTO),
>    ...
> }

using my input from the earlier email (repeated below) the following
'works':

  <widgetspecifications>
  {
    for $spec in $this//SPEC
    return
    <widgetspecification 
      validFrom="{$spec/VALIDFROM/text()}" 
      validTo="{$spec/VALIDTO/text()}">
    </widgetspecification>          
  }
  </widgetspecifications>

however, when I try to incorporate your suggested syntax change:

  <widgetspecifications>
  {
    for $spec in $this//SPEC
    return
      element widgetspecification {
        attribute validFrom $spec/VALIDFROM/text(),
        attribute validTo $spec/VALIDTO/text()
      }
  }
  </widgetspecifications>

I get an error.

I'm using BEA's engine which is based on the August 16, 2002 draft.  Does
the above rely on something in a newer version of the draft, or should it
work on that version?  Or - am I just missing something completely?

Am I right in thinking that the above is defined at
http://www.w3.org/TR/2002/WD-xquery-20020816/#id-sequencetype ?

thanks again,

input document:

  <SPECS>
    <SPEC>
      <VALIDFROM>20020801</VALIDFROM>
      <VALIDTO>20020815</VALIDTO>
      <morestuff />
    </SPEC>
    <SPEC>
      <VALIDFROM>20020816</VALIDFROM>
      <VALIDTO>99991231</VALIDTO>
      <morestuff />
    </SPEC>
