Canonical EXI

TK: I added unsigned integer test cases.

DP: I also noticed datetime test case changes.
... Maybe related to the latest changes.
... I noticed one issue on my side on fractional seconds.

TK: It was not using the correct schema.
... I will work on string table test cases.
... OpenEXI implements datetime normalization, but has not been enabled yet at this moment.

EXI4JSON

DP: I played around with the mapping.
... I currently use JSON schema.
... You sometimes want to allow additional field names.
... It somehow conflicts with XML schema.
... We need to use <all/> for JSON.
... We want to add <any/> but it is not allowed in XSD 1.0.

TK: Can we define like "anything" element?

DP: Once you add "anything" element, JSON instances are different between schema-less and schema-informed.

TK: Can we use <choice/> instead?

DP: This might work.
... I started to work on JSON-schema for WoT TD.
... That's where I found the issue.
... Section E now describes best practices to describe EXI4JSON in JSON-schema.
... Like "anyOf" requires back-tracking.

TK: Next telecon will be probably on July 4th.
... Let's have short technical discussion on Canonical EXI if we can.
