How to implement SDMX 2.1

[Tungurahua]

rsdmx currently supports SDMX 2.0 only. Being able to parse SDMX 2.1 would be needed to connect to the REST service at Eurostat as it is only available for SDMX2.1. This raises several questions:

• are there any reasons not to implement SDMX 2.1
• is it sensible to have both versions of the standard (and possible future updates) available in the package
• How could parsing SDMX2.1 be made possible without changing the existing interface.

How do you feel about this?

rsdmx should also implement SDMX 2.1, and especially as the need is explicitely expressed now. Enabling SDMX 2.1 requires several steps:

• validating a SDMXSchema object with value 2.1, at now only set to 2.0,
• check existing implementation (a quick check, it seems they are error when parsing)

I will investigate this further ASAP, also because i need to think the best way to architect the parsers when dealing with 2 schema versions.

@Tungurahua As i think it's something more than useful, at least to initiate the move to SDMX 2.1 support, i've worked a bit on this, and performed tests based on a Eurostat sample. If you can, reinstall rsdmx from master and try the new code.

@eblondel Great! I used this for some further Eurostat data (see #16 ) and it looks ok. I will do some further testing the upcoming days
