Hi Mrinal,

As Markus mentioned, the example URIs in the spec that contain semicolons
aren't DIDs themselves, they are DID-based Service URIs. (The semicolon is
a proposed mechanism to separate the DID part from the service locator
part). Take a look at the discussion at that PR #90, it goes into details.
