Detailed Description

The order where Token subtypes are declared should be:

• literal terminals
• option & co
• pkt field & co
• ==
• substring & co
• not, and, or Token representing a constant string

This token holds value of a constant string, e.g. it represents "MSFT" in expression option[vendor-class].text == "MSFT"
