@ngdoc error
@name $compile:uterdir
@fullName Unterminated Directive
@description

This error occurs when using multi-element directives and a `directive-start` attribute fails to form a matching pair with a corresponding `directive-end` attribute.
A `directive-start` should have a matching `directive-end` on a sibling node in the DOM. For instance,

```
<table>
  <tr ng-repeat-start="item in list">I get repeated</tr>
  <tr ng-repeat-end>I also get repeated</tr>
</table>
```

is a valid example.

This error can occur in several different ways. One is by leaving out the `directive-end` attribute, like so:

```
<div>
  <span foo-start></span>
</div>
```

Another is by nesting a `directive-end` inside of `directive-start`, or vice versa:

```
<div>
  <span foo-start><span foo-end></span></span>
</div>
```

To avoid this error, make sure each `directive-start` you use has a matching `directive-end` on a sibling node in the DOM.
