Section 3.5.3. says:
If there are multiple key leaf values, the path segment is constructed by having the list name, followed by the value of each leaf identified in the "key" statement, encoded in the order specified in the YANG "key" statement. Each key leaf value except the last one is followed by a comma character.
It should say:
If there are multiple key leaf values, the path segment is constructed by having the list name, followed by an "=" character, followed by the value of each leaf identified in the "key" statement, encoded in the order specified in the YANG "key" statement. Each key leaf value except the last one is followed by a comma character.
Notes:
When describing the encoding of key values for a list, in the case of multiple keys the "=" equal sign is not mentioned although it is used in the examples.

It should say:

Notes:
The quoted text occurs twice; p 128 and p 130.
The leaf "gap" is defined as type decimal64 in A.1. According to RFC 7951, section 6.1, a decimal64 type is represented as a string in JSON.

Section 4.3 says:
If a retrieval request for a data resource representing a YANG leaf-list or list object identifies more than one instance and XML encoding is used in the response, then an error response containing a "400 Bad Request" status-line MUST be returned by the server. The error-tag value "invalid-value" is used in this case. Note that a non-configuration list is not required to define any keys. In this case, the retrieval of a single list instance is not possible.
Notes:
This whole paragraph should be removed because, according to Section 3.5 (Data Resource), the "list" and "leaf-leaf" themselves are not a data resources:
A data resource represents a YANG data node that is a descendant node
of a datastore resource. Each YANG-defined data node can be uniquely
targeted by the request-line of an HTTP method. Containers, leafs,
leaf-list entries, list entries, anydata nodes, and anyxml nodes are
data resources.
No GET, PUT, POST, DELETE, or PATCH example in the RFC illustrates an operation on a "list" or "leaf-list" directly (i.e., without a key, which would then represent an element of the list or leaf-list).

Section 4.5 says:
The "insert" (Section 4.8.5) and "point" (Section 4.8.6) query parameters MUST be supported by the PUT method for data resources. These parameters are only allowed if the list or leaf-list is "ordered-by user".
It should say:
The "insert" (Section 4.8.5) and "point" (Section 4.8.6) query parameters MUST be supported by the PUT method for data resources. These parameters are only allowed if the target resource is a non-existent entry of an "ordered-by user" list or leaf-list.
Notes:
First, Section 3.5 (Data Resource) says that "list" and "leaf-leaf" are not a data resources:
A data resource represents a YANG data node that is a descendant node
of a datastore resource. Each YANG-defined data node can be uniquely
targeted by the request-line of an HTTP method. Containers, leafs,
leaf-list entries, list entries, anydata nodes, and anyxml nodes are
data resources.
Second, these query parameters only make sense when targeting a non-existent entry. If the entry does not exist, then PUT is being used like a POST: to create and place an item in an ordered list. However, if the entry exists, then PUT is being used to both replace the contents and (presumably) re-place the order in the list; but this doesn't make sense because:
1) "insert" defaults to "last".
2) there is no "insert" value to indicate "keep existing placement".
3) having to concoct valid "insert" and "point" values is hard.
Thus indiscriminate PUTs would move entries to the end, which can't be desired...

Section 4.8.5 says:
The default value is "last".
It should say:
The default value is “last”, except when used with PUT and the target resource already exists, in which case the default is to replace the target resource without altering its position in the "ordered-by user” list or leaf-list.
Notes:
The "last" default is intended for when creating a new element.
A PUT operation that replaces a list or leaf-list entry should not move the entry unless the "insert" parameter is explicitly passed.

Notes:
Add missing-element to the table Mapping from <error-tag> to Status Code

The NETCONF error-tag missing-element is not listed in the table mapping
error-tag to HTTP status code. This seems to be a mistake since all other
error-tags are listed (even the obsolete partial-operation which should not
be used according to RFC 6241).

It should say:

Notes:
The error-tag value should be corrected as "data-exists" in this case
based on the context. According to error-tag definition in RFC6241:
error-tag: resource-denied
error-type: transport, rpc, protocol, application
error-severity: error
error-info: none
Description: Request could not be completed because of
insufficient resources.
It is apparent error-tag value "data-exists" should be corresponding
to the data resource already exists condition.
