CAB subnode identification
BNF grammar definitions:
id ::= ( "" | <array-index> "." ) <regular-id> array-index ::= "[" <integer> "]" <opt-array-index> opt-array-index ::= <array-index> | "" regular-id ::= <dic-name><opt-array-index> ( "" | "." <regular-id> ) dic-name ::= <a sequence of any character except of ".">
A subnode of CAB dictionary is identified by a string of <dic-name>
syntax.
A subnode of CAB array is identified by an integer index.
Additionally a generic multi-level subnode identification is supported through a string of <id>
syntax.
Examples:
"name1"
"[0]"
"name1.name2[0][1].name3"
"[0].name4[1]"
