I noticed the same thing when I made turned skmMenu into a user control. It doesn't appear to cause any problems.

>I added a user control to an asp.net page. User control has property such as SelectedMenuItemStyle. I go to the property window of this control, set some values (Height, ForColor, etc). Then when I look at the HTML code of the page, it looks like this:
>
>

><SelectedMenuItemStyle Height="100px" ForeColor="White" BackColor="Black"></SelectedMenuItemStyle>
>

>
>But the name SelectedMenuItemStyle is red-underlined (I forgot what it is called) and when I move the mouse over it, the tooltip message says
>"The active schema does not support the element 'SelectedMenuItemStyle'"
>
>Why? Is this a benign problem or symptom of something not installed?
>
>TIA.
