Hi all,
I've found something strange that I cannot explain to myself. See the
code below:

[ParseChildren(true)]
public class MyControl : Control, INamingContainer
{
    public MyControl() : base() {}

    private HeaderTemplateCreator _header;
    public HeaderTemplateCreator Header
    {
        get { return _header;}
        set { _header=value; }
    }

    private FooterTemplate _footer;
    public FooterTemplate Footer
    {
        get { return _footer; }
        set { _footer=value; }
    }

    protected override void CreateChildControls()
    {
        Controls.Clear();

        if (Header!=null)
        {
            Header.InstantiateIn(this);
        }

        if (Footer!=null)
        {
            Footer.InstantiateIn(this);
        }
    }
}

// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public class HeaderTemplateCreator : ITemplate
{
    public void InstantiateIn(Control container)
    {
        container.Controls.Add(new HeaderTemplate());
    }
}

public class HeaderTemplate : Control, INamingContainer
{
    public HeaderTemplate() : base()
    {
    }
}

// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public class FooterTemplate : Control, INamingContainer, ITemplate
{
    public FooterTemplate() : base()
    {
    }

    public void InstantiateIn(Control container)
    {
        container.Controls.Add(this);
    }
}

I place this control in .asxp as follows:

<uc:MyControl id="mc" runat="server">
    <header>
    </header>
    <footer>
        blah-blah<br>
        <asp:Label ID="label1" Runat="server" text="some text" />
    </footer>
</uc:MyControl>

This works properly. But when I try to put some content in "header" tag
like:

<uc:MyControl id="mc" runat="server">
    <header>
        SOME_TEXT_HERE
    </header>
    <footer>
        blah-blah<br>
        <asp:Label ID="label1" Runat="server" text="some text" />
    </footer>
</uc:MyControl>

I get the following error:
Parser Error Message: Literal content ('SOME_TEXT_HERE') is not allowed
within a 'HeaderTemplateCreator'.

This is pretty strange to me as I cannot see any major difference
between HeaderTemplate (+HeaderTemplateCreateor) and FooterTemplate
classes. If someone can explain this to me I will be very grateful.
Thanks.
