Actually at the bottom not that many features are required, basic is simple:
 - Graphical symbols with pins.
 - Possibility to connect pins or more abstract connection points.
 - Buses to bunch together like wires in a cable.
 - Possibility to assign values to objects.

 - The connections will form nets.

Workflow specific:
 - Which graphical symbols should be available.
 - Attribute assignment.
 - Design rule check which may be done online.

The basics above could be used for schematics of many types, electric, hydraulic, some software diagrams like VHDL and probably more.

Yes. There are some differences above but at the bottom it still the same.
