* New JSON parsing API, with same signature as XML parsing:
   * `clixon_json_parse_string()`
   * `clixon_xml_parse_file()`
* XML YANG binding API have been rearranged as follows:
   * `xml_bind_yang_rpc()`

@ -76,23 +76,28 @@ features include optimized search functions and a repair callback.
* If you have used, `ys`, add `xml_spec_set(x, ys)` after the statement
* If you have `xml_type_set(x, TYPE)` after the statement, you can remove it and set it directly as: `xml_new(name, xp, TYPE)`
* `xml_type_set()`has been removed in the API. The type must be set at creation timw with `xml_new`
* `clicon_rpc_generate_error()` renamed to `clixon_netconf_error()` and added a category parameter
* All uses of `api_path2xpath_cvv()` should be replaced by `api_path2xpath()`
* `api_path2xpath()` added an `xerr` argument.
* Parse and validation API more capable
* `xml_spec_populate` has been split into a family of functions
* `xml_bind_yang_rpc()`
* `xml_bind_yang_rpc_reply()`
* `xml_bind_yang0()`
* `xml_bind_yang0_parent()`
* `xml_bind_yang()`
* `xml_bind_yang_parent()`
* All have three-value return values: -1: error, 0: parse OK, 1: parse and YANG binding OK.
* `xml_parse` and `json_parse` API changes
* Three value returns: -1: error, 0: parse OK, 1: parse and YANG binding OK.
* Extended `xml_parse_file2` and `xml_parse_string2` extended API functions with all options available.
* New concept called `yang_bind` that defines how XML symbols are bound to YANG after parsing
* Existing API same except `xml_parse_file` `endtag` argument moved to `xml_parse_file2`
* Changed `clicon_session_id_get(clicon_handle h, uint32_t *id)`
* XML and JSON parsing functions have been rearranged/cleaned up as follows:
* Three value returns: -1: error, 0: parse OK, 1: parse and YANG binding OK.
* New concept called `yang_bind` that defines how XML symbols are bound to YANG after parsing (see below)
* New XML parsing API:
* `clixon_xml_parse_string()`
* `clixon_xml_parse_file()`
* New JSON parsing API, with same signature as XML parsing:
* `clixon_json_parse_string()`
* `clixon_xml_parse_file()`
* Yang binding type has been introduced as a new concept and used in the API with the following values:
* `YB_MODULE` : Search for matching yang binding among top-level symbols of Yang modules
* `YB_PARENT` : Assume yang binding of existing parent and match its children by name
* `YB_NONE` : Don't do YANG binding
* XML YANG binding API have been rearranged as follows:
* `xml_bind_yang_rpc()`
* `xml_bind_yang_rpc_reply()`
* `xml_bind_yang()`
* `xml_bind_yang0()`
* All have three-value return values: -1: error, 0: YANG binding failed, 1: parse and YANG binding OK.
