IMPLICIT means that the next tag encountered should not be transmitted when
the record is encoded.
So
Pooh [1] IMPLICIT Bah
Bah ::= SEQUENCE {
stuff [1] IMPLICIT INTEGER
}
turns into Pooh [1] IMPLICIT SEQUENCE {stuff [1] IMPLICIT INTEGER}
When you remove the tags that follow the IMPLICIT's, the tagging turns into
[Context 1] [Context 1]
The tag that follows an IMPLICT doesn't need to be a Universal tag.
