I hope this helps . because when you have set replace: true an actual directive div then it is div get replaced by template and its attribtes get merged
for example add class your to outer div of template
code :
 <div class="yes" data-ng-if="errors">---------------------
                                                           |
                                                           | 
      and your directive div is  below                     > replaces and attributs are merged
                                                           |  
    <div show-errors errors="main.errors"></div> ----------
<div show-errors="" errors="main.errors" 
      class="yes ng-binding ng-scope" data-ng-if="errors">...</div>

Basic Difference Between transclude : true and replace: true in Angular Js

Basic Difference Between transclude : true and replace: true in Angular Js

Hope this helps When you use transclude, you are including any html that is available inside your custom tags on your page. For example, if you had:
code :
<person><p>some text</p></person>
template: '<div ng-transclude></div>',
<div><p>some text</p></div>
<person class="ng-isolate-scope"><div ng-transclude=""><p class="ng-scope">some text</p></div></person>
<div ng-transclude="" class="ng-isolate-scope"><p class="ng-scope">some text</p></div>
How exactly replace:true works with element directives?

This might help you Are you sure you have checked that attributes are also replaced?
if you set attributes on directive that will be replaced with but attributes will remain there like
This is the template
code :
angular.module('app', [])
        .directive('someWidget', function () {
            return {
                restrict: 'E',
                replace: true,
                template: '<div>This is the template</div>',
                link: function (scope, element) {
                 
                  
                }
            };
        });
.orange{color:red;}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
    <div ng-app="app">
    <some-widget class="orange red">
       
       
    </some-widget>
      </div>
<div data-some-widget></div>
 restrict: 'A'
Alternatives to replace:true for angularJS directives

Alternatives to replace:true for angularJS directives

I wish did fix the issue. First, I don't think replace: true is getting removed in the near future. It has been deprecated, but getting rid of it in any angular 1.X release would be a breaking change so I think you're ok until Angular 2.0 is released. Angular 2.0 is going to break a lot more than that, so I wouldn't worry too much about how to make existing apps work without replace: true. It's likely that 2.0 will have some kind of equivalent functionality, but migrating an existing app to 2.0 will probably not be something you'll want to do.
However, to answer your question hypothetically:
code :
<div some-directive ng-click="doSomething()"><div>
<div ng-click="doSomethingInDirective()"></div>
if (directive.replace) {
            replaceDirective = directive;
            if (jqLiteIsTextNode(directiveValue)) {
              $template = [];
            } else {
              $template = removeComments(wrapTemplate(directive.templateNamespace, trim(directiveValue)));
            }
            compileNode = $template[0];

            if ($template.length != 1 || compileNode.nodeType !== NODE_TYPE_ELEMENT) {
              throw $compileMinErr('tplrt',
                  "Template for directive '{0}' must have exactly one root element. {1}",
                  directiveName, '');
            }

            replaceWith(jqCollection, $compileNode, compileNode);

            var newTemplateAttrs = {$attr: {}};

            // combine directives from the original node and from the template:
            // - take the array of directives for this element
            // - split it into two parts, those that already applied (processed) and those that weren't (unprocessed)
            // - collect directives from the template and sort them by priority
            // - combine directives as: processed + template + unprocessed
            var templateDirectives = collectDirectives(compileNode, [], newTemplateAttrs);
            var unprocessedDirectives = directives.splice(i + 1, directives.length - (i + 1));

            if (newIsolateScopeDirective) {
              markDirectivesAsIsolate(templateDirectives);
            }
            directives = directives.concat(templateDirectives).concat(unprocessedDirectives);
            mergeTemplateAttributes(templateAttrs, newTemplateAttrs);

    return {
        link: function (scope, e, a) {
          scope.my.info.e.push(e);
          scope.my.info.a.push(a);

          console
          $timeout(function(){
            if(a.id == "navRadio_sa") {
              e.prop("checked", true);
              var me = (a.id).replace("navRadio_","");
            }            
          }, 10);

        }
    }

});
How to substitute deprecated replace-property in Angular directives

How to substitute deprecated replace-property in Angular directives

This might help you There used to be a replace-property for directives in Angular, which is now deprecated. , That will give you same output as the directive with replace: true
code :
angular.module('myModule')
    .directive('myDirective', myDirectiveCtrl);

function myDirectiveCtrl() {
    return {
        'restrict': 'A',
        'scope': false,
        'template': 'content',
        'link': function () {}
    };
}
<div><span my-directive></span></div>
<div>
  <span></span>
  <p></p>
</div>
<span></span>
<p></p>
