Re: [netmod] validating instance data against YANG schema including 'must' statements
Hi Jason, yanglint does validate XML instance data for must statements: MAHESH-M-M8D1:/Volumes/External/git/my-YANG-public/src/model/draft *833 > yanglint -t auto -s -i -p common .../../../build/mef-legato-servi...@2018-07-17.yang MEF6.2-bwp-per-uni-mef-interface-configuration.xml err : Must condition ". >= 1 and . <= count(../../bwp-flow/rank)" not satisfied.

Re: [netmod] validating instance data against YANG schema including 'must' statements
Thx Lada. If I only have XML (e.g. from a NETCONF interface) I suppose I could use yanglint, e.g. this type of usage: yanglint--format=json--type=config --output=data.json ./all-my-modules/*.yang ./data.xml Is that correct? I believe yanglint can also validate instance data against a YANG schema. Can anyone confirm that yang2dsdl and yanglint do *not* validate against the 'must' statements?

Do > those tools also work with YANG 1.1 modules? Yangson does a complete validation, and supports YANG 1.1, but only JSON representation of instance data.
