<p>I want to set up an ASP.NET custom control such that it has a custom name, specifically, with a hyphen within it, so it might look like this in markup:</p>

<pre><code>&lt;rp:do-something runat="server" id="doSomething1" /&gt;</code></pre>

<p>I don't mind if this syntax requires setting up a tag mapping in web.config or something to that effect, but the <a href="http://msdn.microsoft.com/en-us/library/ms164641.aspx" rel="nofollow noreferrer" title="tagMapping Element">tagMapping element</a> doesn't quite match up for what I'd like to do.</p>

Try replacing &Alpha with
```
```
&#913;
```
```
