Re: [DMM] YANG validation issue in draft-ietf-dmm-fpc-cpdp-06.txt

["Bertz, Lyle T [CTO]" <[e-mail]>]

We changed that this morning and tested but got the same response form the yangvalator site.  Thus, it appears we are then fighting a caching bug on yangvaldator site.  Although our I-D toolchains are evolving, I think having multiple toolchains is a bit problematic here as authors are shadowboxing.  We'll make the update but is there a way to get an official toolchain established that authors can point to?  

The I-D tool is not using the same tool set others, who are commenting on errors/issue, are.  This makes YANG development a bit more problematic as we go from a 'it worked on this chain but not that one...' situation.  If the answer for now is 'maintain your own toolchain' that is fine but I would encourage public access on how to maintain a good chain (or a github project on the chain) and push awareness, at least once, beyond netmod wg as more working groups pick up YANG.

Hi,
some notes to warnings from yanglint:

- each two warnings are actually connected in this case, so let's look to the first issue:
warn: Schema node "attributetype" not found (../attributetype).
warn: Invalid when condition "../attributetype = 'Per-MN-Agg-Max-DL-Bit-Rate-type'". (/ietf-dmm-fpc:tenants/tenant/fpc-mobility/contexts/ul/qos-profile-parameters/value/ietf-dmm-fpc-pmip:qos-pmip/attribute-choice/per-mn-agg-max-dl-case) 

- attributetype node, used in the when condition as "../attributetype", was not found
- the when condition is placed in the node with the path printed at the end of the second message in the brackets
- when you look into the schema, the node with when is actually placed into ietf-dmm-fpc-pmip via uses in one of the augments, used grouping qosattribute is from ietf-pmip-qos
- so the actual bug is in ietf-pmip-qos schema in grouping qosattribute - instead of ../attributetype there should be ./attributetype because the context node for the when in case statement is the closets ancestor node to the node with the "when" statement that is a data node

Regards,
Radek
