Sure - that was just for clarification of how the PUT is done with browsers :)

I was just thinking about the possible CRUD REST schemas and it found
that under that schema you display the same form under two addresses:
/foo/1234/edit_form and /foo/1234 (in case of the error).  And the
other day I had that idea that perhaps instead of using path part -
use another parameter so /foo/1234?x-view-method=edit_form  would
render the form and /foo/1234 would render the standard view of the
object.   This way the form would have just one address.

Both things are just different representations of the same thing - so
using a parameter to differentiate between them seems quite logical.
But on the other hand it might look too different from the traditional
ways.
