You are correct Nathan in that the current implementation does not  
supply the field names.

I look at the Bridge as a work-in-progress.  It is not so much what it  
does today as what it will be able to do once a few tool builders  
start working with it.  If Joe wasn't so anti-PHP he might look to get  
some business out of adapting his current tooling and make some really  
nice extensions to it! <grin>

Bridge uses the WebFacing API and that API does not supply names -  
just access to the basic workstation buffer.  Zend's code wraps that  
data into an XML stream and that is what is presented to the PHP  
code.  WebFacing requires the DDS in order to obtain the field name  
and other details - obviously Bridge could also be extended to do that  
or work from DSPFFD type information.
