LINK VOTable element for DATALINK

[Patrick Dowler]

<FIELD ID="name" name="Name" ucd="meta.id;meta.main" datatype="char"
           arraysize="32" width="32">
     <DESCRIPTION>Solar system object name</DESCRIPTION>
     <LINK
 
href="http://vizier.u-strasbg.fr/cgi-bin/VizieR-5?-source=B/astorb/astorb&Name===${Name}"/>
</FIELD>

In the case we are discussing, the PARAM-LINK stuff is in a separate 
resource from the FIELD(s) and a service description could have multiple 
PARAM-LINK pairs. The DataLink case specifically has only one which is 
deceptively too simple. IT is not in general a special link involving a 
single FIELD, as the above example shows.


See also my response in main thread about the content-role. I don't 
think it is technically needed to describe the service.
