Hi,
Section 10 of the YANG RFC covers updating modules while maintaining
backwards-compatibiility. I have a question about whether the following
statement allows for a string type to be replaced with a union comprising
solely of string types, so long as the overall set of strings accepted was no
more restrictive? This would allow us to reuse some existing types.
o A "type" statement may be replaced with another "type" statement
that does not change the syntax or semantics of the type. For
example, an inline type definition may be replaced with a typedef,
but an int8 type cannot be replaced by an int16, since the syntax
would change.
I can see that changing int8 to int16 changes the syntax, but does changing
from string to a union of strings change the syntax according to this
definition?
Thanks,
William
