Lastly, an attribute value can be set in a note. Although other notes may use the same value for the same attribute this is coincidental. The note with a local value is now no longer inheriting a value for that attribute. Note though that inheritance is per attribute. Even if one or more attributes have a local value, all other attributes still retain their inheritance.
For most users, this is the context wherin you undertake the majority most of your editing of attribute values. Attributes can also be altered by action code as well as by manual edit or inheritance.
Note that the cascade does not need to use prototypes…
