angularjs - The angular documentation says that restrict applies to attributes (A) and elements (E). The source code says (AC) - why? -

the angular documentation says restrict applies attributes (a) , elements (e).

restrict

string of subset of eacm restricts directive specific directive declaration style. if omitted, defaults (elements , attributes) used.

e - element name (default): <my-directive></my-directive>

a - attribute (default): <div my-directive="exp"></div>

c - class: <div> class="my-directive: exp;"></div>

m - comment: <!-- directive: my-directive exp -->

the source code says (ac) - why discrepancy, or misreading code?

function ngdirective(directive) {   if (isfunction(directive)) {     directive = {       link: directive     };   }   directive.restrict = directive.restrict || 'ac'; // here   return valuefn(directive); } 

directives you create yourself restricted being used elements or attributes default.

the registerdirective function in compile.js contains code relevant documentation snippet you've posted (i.e. custom directives default restrict elements , attributes).

and @jhecht mentioned, it's built-in directives (i.e. ng-repeat, ng-style, etc.) restricted attributes , comments default.
