FYI - below is a tool that converts W3C XML Schema documents
into ISO/ITU-T X.694 compliant ASN.1 schema.
Sun and other middleware vendors plan to enhance their middleware
to send ONLY ASN.1 encoded schema and instances over the wire (to
improve performance and interoperability).
Sun has already benchmarked 20-to-1 performance improvements
over the wire with XML Schema instances converted to ASN.1.
This tokenization is comparable to the WAP-defined tokenization
currently done for wireless access to HTML-based web pages.

Subject: [asn1xml] New XSD to ASN.1 conversion tool on the ASN.1 website
The ASN.1 information website announces the availability of xsdasn1, a
new XSD to ASN.1 conversion tool at
This tool, contributed by OSS Nokalva, converts XML Schemas to ASN.1
modules, as specified in ITU-T Rec. X.694 | ISO/IEC 8825-5 at
The xsdasn1 tool replaces the previously available, but now outdated,
prototype developed by France Telecom R&D to help develop the X.694
The web interface for this tool is quite new, so please accept our
apologies in case of any problems. We'll do our best to correct the bugs
