🗒️Logical notations

What different notations on different pages mean.

• ^_(MANDATORY) – must necessarily be specified in the action/placeholder;

• ^{_{(SEMI-MANDATORY)}} – must necessarily be specified in the action/placeholder provided that some other option is specified (that is, if another option is specified in some wrong value or not specified at all depending on the requirements, the current value does not need to be specified, but if it is specified in the required value, it is necessary);

• ^{_{(SEMI-OPTIONAL)}} – can optionally be specified in the action/placeholder provided that some other option is specified (that is, if another option is specified in some wrong value or not specified at all depending on the requirements, it is not necessary to specify the current value, and if it is specified in the required value, it can be specified optionally);

• ^{_{(SEMI-OPTIONAL | SEMI-MANDATORY)}} – can optionally be specified in the action/placeholder provided that some other option is specified to some value, or must necessarily be specified in the action/placeholder provided that some other option is specified to some another value (that is, if another option is specified in some wrong value or not specified at all depending on the requirements, it is not necessary to specify the current value, but if it is specified in the required value, it is necessary);

• ^_(OPTIONAL) – can optionally be specified in the action/placeholder.

The concepts used from action to action may vary depending on the implementation of the explanation of the format and principle of operation of the action.
