[mungayree]

Can existing prettyPrintType be enhanced to print XML/JSON ?

    print p.prettyPrintType()

from prettyPrintType() into XML below with some prettyPrintTypeXML() as ---
Same can be done prettyPrintTypeJSON().

I think it should be fairly easy to do for both XML and JSON. I may be able to look into that unless you come up with a PR. ;-)

In the grand scheme of things there will eventually be a "codec" which could turn pyasn1 object tree into JSON/XML in the same way as it currently does BER/DER/CER serialization. Because, logically, JSON/XML is just another form of data serialization.

hey all, just a greedy ask, has this been implemented?
