The following errata report has been submitted for RFC7950,
"The YANG 1.1 Data Modeling Language".

You may review the report below and at:

Type: Technical
Reported by: Ladislav Lhotka <lhotka@nic.cz>

Section: 3

Original Text
o  schema tree: The definition hierarchy specified within a module.

Corrected Text
o  schema tree: The hierarchy of schema nodes defined in the set of all modules 
   implemented by a server, as specified in the YANG library data [RFC7895].

The original definition of the term has two problems:

1. Schema tree is not limited to a single module. Some YANG constructs, such as augment and leafref type, may refer to a schema node that is defined in another module.

2. Apart from schema nodes, YANG modules contain definitions that do not contribute to the schema tree: groupings, typedefs, identities etc.

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
