I would prefer if we also allowed for version types themselves to be 
dereferencable.  That way, we can accomodate an open versioning 
framework, rather than attempting to define all possible version types.  
This is the way Liberty handles the Attribute-portion of the identity 
framework (ID-WSF: SIS).

so a valid version string may look like:

xri://naming.authority/local/part/[+version/urn:version-authority:dottedalphanum/1.2a]

or even:

xri://naming.authority/local/part/[+version/urn:xri:version-authority:dottedalphanum/1.2a]

etc...  of course, a version-spec referenced as 
xri://version.name.authority/spec/namespace may be difficult for parsers.
