The format of xmi.id is constrained by the XML ID validity constraints:
http://www.w3.org/TR/REC-xml#id.

It must be (a) unique to the document, and (b) a valid NAME:
http://www.w3.org/TR/REC-xml#NT-Name

Which means, it must match this grammar:

     [4]    NameChar    ::=    Letter | Digit | '.' | '-' | '_' | ':'
                                      | CombiningChar | Extender
     [5]    Name        ::=    (Letter | '_' | ':') (NameChar)*

Where also the ":" has been reserved for use for XML Namespaces. So, for 
example, a format such as "Model.Class-123" would be a valid xmi.id.
