Create ASP User Control With Inner Properties Used With Markup Similar To UpdatePanel?

I am creating a user control that I wish to have inner properties as well as normal attributes. Although the actual function of the control has nothing to do with, say, UpdatePanel, I am trying to create something with similar ASPX markup. The developer designing the page should be able to use my control like:

<ns:MyControl ID="someID" runat="server" SomeOtherAttribute="true">
<ContentTemplate>
<asp:Label ID="someLabel" runat="server" Text="Normal page markup and controls should go here" /><br />
<p>This should be OK too.</p>
</ContentTemplate>
<ControlEvent ControlName="idOfOtherControl" Event="Click" />
<ControlEvent ControlName="idOfSomeOtherControl" Event="MouseOver" />
</ns:MyControl>

Also acceptable would be wrapping the ControlEvent tags in some other tag, more like what happens when using UpdatePanel:

<ns:MyControl ID="someID" runat="server" SomeOtherAttribute="true">
<ContentTemplate>
<asp:Label ID="someLabel" runat="server" Text="Normal page markup and controls should go here" /><br />
<p>This should be OK too.</p>
</ContentTemplate>
<ControlEvents>
<ns:ControlEvent ControlName="idOfOtherControl" Event="Click" />........................
