      When creating a UUID in js-bson, regex validation is performed that specifically requires a version 4 UUID format.

      https://github.com/mongodb/js-bson/blob/d9f0eaa243ceeba8dd82e9c3b07fd8bca10cfc44/src/uuid_utils.ts#L6

      The regex used:

      const VALIDATION_REGEX =
        /^(?:[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}|[0-9a-f]{12}4[0-9a-f]{3}[89ab][0-9a-f]{15})$/i;
      

      Why v4 and not a more generic format?   
      Notice specifically in the regext that "4" is required, as is "[89ab]"
      e.g. 00000000-0000-4000-8000-000000000000
       
      This means that a .NET Guid.Empty string value of "00000000-0000-0000-0000-000000000000" served to the js-bson is invalid and an error is thrown when one attempts to construct a UUID with it.


      Node Team Notes:

      AC

      • Reduce the strictness of the regexp to allow any sequence of hex digits with or without dashes
      • Remove bitwise validation from the isUint8Array section of UUID.isValid(uuid)
      • Clarify documentation that new UUID() returns a version 4 UUID
      • Add a test verifying that a UUID can be created from a sequence of bytes and from a string that are not version 4
