No -- apologies I should have been more specific. It was a question regarding the definition of the PermittedAlphabet constraint in X.680: 47.7. Can you actually use any of the known-multiplier character constraints in the construction of a PermittedAlphabet constraint?
Also does the PER-visibility of a constraint also apply wherever it is used in the construction of a constraint? For example, is the SingleValue constraint PER-visible when used to construct a PermittedAlphabet constraint?

You use a set of characters, for instance, IA5String (FROM("a"|"b"|"c")) or IA5String (FROM("abc")) which is equivalent to FROM("a"|"b"|"c") but easier to type when you have larger sets of characters. You can also have ranges like this IA5String (FROM("a".."z")) For unprintable characters you use tuples or quadruples like this IA5String (FROM("abc" | {0,13})) -- {0,13} is carriage return or BMPString (FROM("abc" | {0,0,0,13})) -- also {0,0,0,13} is CR For a complete list of valid characters refer to the ASN1-CHARACTER-MODULE at the link below http://www.itu.int/ITU-T/formal-language/itu-t/x/x680/2008/ASN1-Object-Identifier-Module.html Did I answer your question?
