I predict it will die quietly with no uptake.  ASN.X is a new schema 
language with the syntax of XSD and the semantics of ASN.1 that works with 
the toolkits of neither of them. As I read sections 8 and 9 of RFC 4910, 
RXER can't round-trip text strings, and its primary claim over XER is that 
XER uses the type names in the encoding, and RXER doesn't. If a new 
version of a standard comes along and refactors the schema, then an old 
XER encoding may no longer work.  I'm okay with that, since I think it 
follows the XML use model; your old xsi:type declarations are broken, too. 
 I don't know if it's common for standard revisions in the ASN1 world to 
refactor type declarations; in the security space I haven't seen it 
happen.

At any rate, those RFC's are experimental.  For good reason :)
