Can you explain the distinction between ng-if and data-ng-if?
Although they appear to function similarly, I'm struggling to discern the specific difference as there isn't much information out there on data-ng-if.

Both essentially serve the same purpose, however, when running a validation check on your webpage using the W3C validator tool, if you do not include the data- prefix before your custom attribute, it will result in a failure. This is because the W3C validator does not recognize your custom attribute by default, so you must explicitly state the data- prefix to ensure that the W3C validator can successfully validate your HTML code.
They are considered to be the same. The $compile service connects them to the identical directive.
According to the Documentation:
The normalization process goes like this:
- Remove
x-anddata-from the beginning of the element/attributes.- Change the name delimited by
:,-, or_to camelCase.For instance, the following formats are all interchangeable and correspond with the
ngBinddirective:<div ng-controller="Controller"> Hello <input ng-model='name'> <hr/> <span ng-bind="name"></span> <br/> <span ng:bind="name"></span> <br/> <span ng_bind="name"></span> <br/> <span data-ng-bind="name"></span> <br/> <span x-ng-bind="name"></span> <br/> </div>
