Having a small problem with custom Intellisense

[James Bright]

I have set up custom Intellisense for our project. (In a nutshell, we will
have ASP.NET controls based on many of the statndard WebControls, but with a
few extensions that we will be adding). I've put a custom XSD in the
schemas\xml directory and it works pretty great. It's largely based on the
asp.xsd.

My problem is that while this works great for most controls, providing
Intellisense whenever I have:

<foo:FooTextB ox runat=server... />

I have one nagging problem left. I plan on having a "FooDropDownLis t"
control based on the ASP.NET DrownDownList control. I'd like Intellisense to
only allow <asp:ListItem/> without tagging it as invalid. However, I cannot
override by default prefix of "foo". I've tried several educated guesses, but
I always end up with <foo:ListItem/>. And since ListItem is sealed, I can't
just make a dummy FooListItem.

Here is the xsd that I have so far:

<!-- <foo:DropDownLi st> -->
<xsd:complexTyp e name="DropDownL istDef" vs:noambientcon tentmodel="true ">
<xsd:choice>
<xsd:element name="ListItem" type="ListItemD ef" />
</xsd:choice>
<xsd:attribut e name="BorderSty le" type="BorderSty le" vs:readonly="tr ue" />
<!-- edits... -->
</xsd:complexType >

I'm not a xml/xsd guru, so I'm not sure what I'd need to do to get it to
work. Ideally I'd like the following to be valid (and only the following):

<foo:FooDropDow nList runat=server>
<asp:ListItem>B lue</asp:ListItem>
<asp:ListItem>Y ello</asp:ListItem>
</foo:FooDropDown List>

Thanks in advance. This is the last piece of the puzzle.
