Circular definitions

[Yaroslav Gaydash]

Hello everybody,

Here's piece of MMS (ISO-9506) definition module.

Data ::= CHOICE {
    array     [1] IMPLICIT SEQUENCE OF Data,
    structure [2] IMPLICIT SEQUENCE OF Data,
   ...
} 

Another sample module is attached which shows TypeSpecification and 
TypeDescription mutual use.

So asn1_create_element() call is never return.

Is there a way to handle such circular or mutual use definitions?

Thanks.

Yaroslav Gaydash.
