The brazilian electronic invoicing standard is monstrous not because of
the technology choice, but because the legislation requirements are
ridiculous.
It uses PKI certs for identity, HTTPS client authentication for secure
communication, XMLSig for electronic signing, SOAP for messaging and
XMLSchema to provide a data model. Remember the electronic invoicing
project started back in 2004. The "lightweight" alternative (REST+JSON
instead of SOAP+XML) was on it's infancy. Given the maze that is the
Brazilian tax code, I think they did a good job.
Each state was free to implement the server it the way they wanted -
I've seen it done in .NET, Axis, IBM WebSphere, JBoss. Besides the free
government client implementation, I've seen a number of Delphi
implementations (a popular language in Brazil).
However it's much easier to develop using JAXB or Axis - it generates
the bulk of the object<->xml mappings. Reimplementing it is indeed not
trivial and I don't really think it's need for OpenERP.

Really? In Spain, the API (only Java L ) is OpenSource, I think it
was one of the requirements for each UE country. There is also no
need to sent it to anybody, the JAVA Api helps to build easily
signed invoices, but we can make it from OpenERP also and then
validate with the XSD provided. More theory behind this of course
(different types of signed documents depending on the
specifications versions, 3 ways of delivering the invoice…) but
this is how it should work.
Just a precision, in Brazil the API is open source too. Now, the only
2 usable implementations are Java closed source (though decompilable).
The API isn't trivial at all to re-implement (at least 10 000 lines of
Python required, not to say SOAP + Python + authentication can be a
nightmare). I bet this is rather on purpose (to protect monopolies)
rather than pure stupidity.
