viz Very Extensible Linking Language Unafraid of Markup (VELLUM)

Nevýhodou je poněkud rozvleklejší ("upovídaný", verbose) zápis, než u XLink

VELLUM is aimed exclusively at "external" or out-of-line linking. This frees VELLUM from the constraints imposed by developer expectations for inline linking.

VELLUM accepts the cost of a verbose form in exchange for the extensibility and precision that element forms and indirection can offer.

VELLUM does permit the use of existing abbreviations (like URIs and URI references), but simultaneously allows developers to specify more information than is carried in those identifiers.

VELLUM also looks forward to the prospect of VELLUM processors which maintain state across multiple traversals and permit the creation of interactive hypertexts, not just collections of connections.
