ASN.1

We NOW support ASN.1 generation based loosely on ISO20022-8:2013.
Implementing the specification directly is not completely possible as:

• much of the generation is left unspecified,
  so rely on examples for what is intended;
• some examples do not conform to strict ASN.1 syntax;
• further notation is required to enable compilation;
• an XSD module is not defined, nor referenced.
  We used this xsd.asn from the UBL ASN.1 specification.

Our aim is to acheive interoperability with other syntax encodings.
ie. JER should be compatible with our JSON schema format.
and XER should be compatible with our XML schema format.

In the meantime, please feedback improvements.
