--------------------------------------
Type: Technical
Reported by: Carsten Bormann <[e-mail]>

Section: Appendix A

Original Text
-------------
   oid = text .regexp "([0-2])((\.0)|(\.[1-9][0-9]*))*"


Corrected Text
--------------
   oid = text .regexp "([0-2])((\.0)|(\.[1-9][0-9]*))*"


Notes
-----
Backslashes need to be doubled in CDDL strings (as they are done in Appendix B).

An alternative fix would be to replace \. by [.]

Note that the equivalent fix is not required for

   regtext = text .regexp "([^\*].*)|([\*][^\*].*)|([\*][\*].+)"

as the fact that the single backslashes have no effect is irrelevant here — the backslashes are not needed in the character classes [...].
As an editorial enhancement, the backslashes could be entirely removed from this line.
