field sets

In LID, we chose to elegantly (?) sidestep this issue:
  - the data sharing features in LID are independent of the XML  
document type(s) that may be underneath
  - for common data elements, we picked other people's definitions  
(instead of inventing our own).

For example, for VCard-type information, not surprisingly, we use the  
XML VCard document type that has been floating around for years.

You can very easily plug in your own document type, for whatever  
information you'd like to share. And there is no problem with LID  
sharing the same information through different document types (e.g.  
because you prefer your own VCard format)

All information access can be filtered by data-element-level ACLs, so  
only those people who should get the respective elements.

Re YADIS, each LID "profile" is being mapped into a YADIS  
capability / service, so a LID/YADIS URL advertises which document  
types it supports.
