@ngdoc error
@name $compile:iscp
@fullName Invalid Isolate Scope Definition
@description

When declaring isolate scope the scope definition object must be in specific format which starts with mode character (`@&=<`), after which comes an optional `?`, and it ends with an optional local name.

```
myModule.directive('directiveName', function factory() {
  return {
    ...
    scope: {
      'localName': '@', // OK
      'localName2': '=attr', // OK
      'localName3': '<?attr', // OK
      'localName4': ' = attr', // OK
      'localName5': 'attr',    // ERROR: missing mode @&=
      'localName6': 'attr=',   // ERROR: must be prefixed with @&=
      'localName7': '=attr?',  // ERROR: ? must come directly after the mode
    }
    ...
  }
});
```
