ASN.1 to XML Convertion

I have just opened a career door that leads to ASN.1 which is, it turns and
is new to me, a way to represent structured data much as XML is a way to
represent structured data. Only ASN.1 is, I believe, a little older and was
originally intended as a way to transmit structured data over communications
circuits. ASN.1 has been used as a formalism in RFCs for describing
protocols. ASN.1 is (sometimes?) binary whereas XML is human readable text.
Anyhow, now I've stumbled over a series of public databases that have been
encoded in ASN.1 primarily, I am told, to compress the data, with respect to
the size the databases would be were they encoded as XML. In the world of
Java, there may well be means to traverse an ASN.1 tree (e.g. by using SAX2
events) as there are means in C# to traverse an XML tree. But what about
Microsoft? Does Microsoft offer something that is familiar with ASN.1 or
can translate ASN.1 to XML? My researches using MSDN Library say: NO.

Hi, Mark

My research coincides with yours so far. I've got one possibility still
outstanding, but I am not optimistic. I was able to locate a couple of
other options using the following google search. You might want to give
them a look.

Hi, Mark

If Microsoft has a product that performs ASN.1 to XML conversion, no one I
contacted knows anything about it.

I hope that one of the vendors I mentioned in my previous post has a
product that will meet your needs.

Sincerely,,

It depends on what you call "ASN.1 to XML translation".

1. If you want to translate an ASN.1 schema into an XML Schema (XSD),
this is not needed, for ASN.1 is a schema notation for ASN.1, just as
XSD or RELAX NG are. See for example, "ASN.1, a schema language for
XML", by OSS Nokalva, at
http://www.oss.com/products/exer-whitepaper.pdf

2. If you want to encode ASN.1 data in XML, you just need to use the
XER encoding rules of ASN.1 in place of the (binary) BER. For more
information, see:
http://asn1.elibel.tm.fr/xml/#xml-notation
A list of XER tools is given at:
