Kinds of Keywords

There are two kinds of keywords:
Simple keyword
A keyword that does not contain other keywords; that is, it has no embedded keywords. It is of the form keywordname = value; where value is not a left parenthesis. In the following example, FQ_CP_NAME and NODE_TYPE are simple keywords, but NODE is not.
NODE=(
     FQ_CP_NAME=USIBMNM.NT265
     NODE_TYPE=END_NODE
)
Complex keyword
Contains embedded simple or complex keywords. In the following example, PORT and PORT_LAN_SPECIFIC_DATA are complex keywords.
PORT=(
     PORT_NAME=LAN1_04
     DLC_NAME=LAN
     PORT_LAN_SPECIFIC_DATA=(
          ADAPTER_ID=LAN1
          ADAPTER_NAME=0001
     )
)
