Validation doesn't clear when submitting a literal to a required lookup

[jcoyne]

If you create a new resource using "Sinopia:RT:Demo:SampleResourceFuller" on development (or any template that has a required lookup), then before entering any values you click save. This validates the form. Next fill in all required fields except the required lookup ("Example 10" in this case).

Then enter text in the field and press the search button

Click the "Add ... as literal" link.

Then you see the validation that cannot be cleared and the resource cannot be saved.

The intended behavior is that when a literal is provided for a lookup, it should be validated as a literal. (That is, "Literal required" if the property is required but a value is not provided.)

I believe that we should change the templates so that this type is called "UriOrLiteral" then. Otherwise this is going to cause us trouble in the future when we want to have a URI only type. It will be hard to differentiate the two data shapes without doing that at this time.

Unfortunately, consumers of the data (e.g., rdf2marc) have to assume that a literal may be present when a URI is expected. That is likely to be the case for other sources of bibliographic data in RDF, not just Sinopia.
