Re: [ASN.1] Question on XER encoding of SEQUENCE OF element types

[Rajul Gupta]

Hi Ed,   Look at this, is this something you are looking for ? I think 13.8 is the answer of your question. I may be wrong also.   13.7 Where a "DefinedType" is used as part of notation governed by a "Type" (for example, in a "SubtypeConstraint") then the "DefinedType" shall be compatible with the governing "Type" as specified in clause B.6.2. 13.8 Every occurrence within an ASN.1 specification of a "DefinedValue" is governed by a "Type", and that "DefinedValue" shall reference a value of a type that is compatible with the governing "Type" as specified in clause B.6.2.

"A" is CHOICE here, so it will encoded like ChoiceType. Look at clause 25.5 (Table 5).   Following are the XER encoding of the value notations.   value A ::= a : 1 XER Encoding (Look at clause 28.10) <A>   <a>1</a> </A>   If you have a value notation,   value B ::= {a : 1} XER Encoding (Look at clause 25.3 and 25.5) <B>   <a>1</a> </B>   Further, the encoding of "value" with two elements will be,   value B ::= {a : 1, b : TRUE} <B>   <a>1</a>   <b><true/></b> </B>   I hope this may help you.   Regards,   Rajul Gupta Oss Nokalva (www.oss.com) [EMAIL PROTECTED] 732 302 9669 (x137)   ----- Original Message ----- From: Ed Day To: [EMAIL PROTECTED] Sent: Tuesday, July 02, 2002 9:53 AM Subject: [ASN.1] Question on XER encoding of SEQUENCE OF element types Hi,   In looking at Clause 25 of the 2002 X.680 pre-release, I am unable to determine how an element of a SEQUENCE OF type is to be encoded when a defined type that references one of the ValueList case types is referenced.  For example:   A ::= CHOICE {    a INTEGER,    b BOOLEAN }   B ::= SEQUENCE OF A   Would a single element of choice a with value 1 be encoded as <A><a>1</a></A> or <a>1</a>?   25.6 through 25.8 talk about TaggedType, ConstrainedType, and SelectionType rules, but I see no mention of DefinedType.  Am I missing something?   Regards,   Ed Day Principal Engineer Objective Systems, Inc.
