Specifying RestrictChildren and empty HtmlTargetElement results in an error

[pranavkm]

[RestrictChildren("div")]
[HtmlTargetElement]
public class MyTagHelper : TagHelper
{

}

<p>
    <my>
        <div></div>
    </my>
</p>

Expected: This should render MyTagHelper correctly
Actual: The <my> tag is not allowed by parent <p> tag helper. Only child tags with name(s) 'div' are allowed.

By design. By specifying [HtmlTargetElement] you're saying that the TagHelper applies to every tag.

[pranavkm]

We need to update the docs on that attribute to indicate it's a catch all tag helper.

The doc comments for HtmlTargetElementAttribute could be improved. The default constructor summary should specify what * means - you shouldn't have to read the remarks.

Also, the error message doesn't specify clearly which tag helper is causing the issue. What if you have multiple tag helpers targeting <p>?
