Data type, cardinality questions, typos

[azaroth42]

• Can @context be used on any resource, or only the Annotation. If only Annotation, then conflicting extensions can occur, that could be avoided by limiting the scope of the context definition
• The data type of rights is unclear -- IRI only ? We took out embedded rights statements already, and I can't think of any properties for licenses other than perhaps language and format.
• The cardinality of rights is unclear -- I think it should be 0..1. Currently has a typo.
• Can the via links be objects with further properties, or IRI only ?
• SVGSelector should be SvgSelector
• Cardinality of collection and page properties are unclear e.g. multiple totals should be clearly an error)
