Re: IPFIX and PSMAP information model: applicability field



Dear Falko,
Dear Benoit, dear all,

I agree to remove it from the *-info documents. Nevertheless, I think it
should be moved to the forthcoming guidelines.
  
That would make sense for the I.Es. that clearly belong to a category.

Regards, Benoit.
Cheers,
Falko

Dear all,

The IPFIX IE's have a property that's not directly displayed in the
draft, except in the XML: "applicability".

The history behind this "applicability" field is that it should have
been used as a guideline, expressing whether a specific Information
Element should be used in a data record, an option record or both of
them. However, the property is used in [IPFIX-INFO] without any
definition - except the values are "option", "data" and "all".

While working on the PSAMP information elements, we concluded that this
"applicability" field doesn't make sense anymore.
1. It's a guideline anyway, not a specification
2. It's present in the XML text only, while the non-XML text is the
authoritative source
3. There are no definitions

So the proposal is to remove this "applicability" field from both
[IPFIX-INFO] and [PSAMP-INFO].
Feedback?

Regards, Benoit.
