Description

A schema.uid() (naming open to suggestions) can be useful for pages that need unique ids localized to the document, e.g. for the id="" attr on a page. The field should accept a "tag" or "category" so that multiple groupings of uids can be created for different purposes.

When two or more fields use the same uid value, the CMS should issue a warning, or if the field is meant to intentionally refer to another field in the CMS, we should have some way of linking to the relevant field.
