Re: Alternative to x!y

/ Jeni Tennison <jeni@jenitennison.com> was heard to say:

|
| <p:input port="document" source="validated!result" />
|

|
| <p:input port="document" source-step="validated" source-port="result" />
|
| This is good for validation (it's possible to put together identity
| constraints on separate attributes whereas it isn't for the x!y

| (source-step defaults to the immediately preceding step, source-port
| to the primary output).
|
| On the other hand, it's a lot more verbose.

Yeah, I'm not naturally moved in that direction.
