RESTCONF Protocol draft-ietf-netconf-restconf-09

Examples:

container top {
list list1 {
key "key1 key2 key3";
...
list list2 {
key "key4 key5";
...
leaf X

}
}
}
For the above YANG definition, URI with key leaf values will be
encoded as follows (line wrapped for display purposes only):
/restconf/data/example-top:top/list1=key1val,key2val,key3val/
list2=key4val,key5val/X

The following example shows how reserved characters are percent-
encoded within a key value. The value of "key1" contains a comma,
single-quote, double-quote, colon, double-quote, space, and forward
slash. (,'":" /). Note that double-quote is not a reserved
characters and does not need to be percent-encoded. The value of
"key2" is the empty string, and the value of "key3" is the string
"foo".

Example URL:

/restconf/data/example-top:top/list1=%2C%27"%3A"%20%2F,,foo
