[Instantrails-developers] RESOLVED - id uniqueness requirement

[Bill Walton]

>From the W3C HTML 4.0 spec at 
http://www.w3.org/TR/REC-html40/struct/global.html#adef-id

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a 
document.

That's enough for me since the observe_field() documentation does say that 
the field to observe is identified by 'field_id'.  The documentation could 
be improved, but I see now that neither it nor the implementation is 
incorrect in this respect.

Best regards,
Bill
