Is it a normal behavior?

Hi eduardpo,

Reproducing your issue is key to understand it and fix it.

I looked for a fresh version of ietf-netconf.yang and found https://yangcatalog.org/yang-search/module_details/ietf-netconf

With this model, there seems to be no issues:

pyang --plugindir $PYBINDPLUGIN -f pybind -o outputs/binding.py models/ietf-netconf@2011-06-01.yang

How are you calling pyang and pyangbind from pyang-binder? An equivalent call to pyang works?

Looking forward to helping you with the issue.

Hi eduardpo,

My bad, I missed the title of the issue, stating that you use '--build-rpc' option. Then I have the same error as you reported.

'pyang --build-rpcs' would ' Generate class bindings for the input and output of RPCs defined in each module. These are placed at the root of each module'. I have first need to understand this to track and identify the Exception you reported.

I think the problem is that pyangbind expects the childless elements to have a 'type' defined, but 'anyxml' and 'anydata' do not have it.

Checking for the presence of 'type' before trying to build the element would fix this.

I was reading https://www.rfc-editor.org/rfc/rfc6020.html#section-7.10, and it seems this Issue is about implementing the 'anyxml' statement.
