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.name2[0][1].name3"
"[0].name4"
