Re: [xsl] How to incrementally add to a result document?

["Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I would represent the log as a global map variable and place any action
there as an entry like  {action-key, action-info}, immediately on
completing each action.

Finally, when the processing is finished, we can produce  from  the
log-map  a single result-document that contains all entries of the log-map.

Thanks,
Dimitre
