Validation Schemas in VS 2005 RRS feed

    Have previously asked this elsewhere (http://social.msdn.microsoft.com/Forums/vstudio/en-US/dcc09022-c102-43ea-a354-a43ebf9fccac/validation-schemas-in-vs-2005?forum=tfsgeneral#e315794c-c85a-416e-bbd5-8a1d4a1f8b41) but been told to re-post here.

    I'm Using Visual Studio 2005 (yes I know ancient)


    Microsoft Visual Studio 2005
    Version 8.0.50727.762  (SP.050727-7600)

    And am looking to introduce schema.org microdata format tags to add additional information for search engines.

    My problem though is that  VS2005 won't compile the pages - complaining of errors e.g.

    "Validation (Internet Explorer 6): Attribute 'itemscope' is not a valid attribute of element 'div'."

    Pre schema.org notation:

    <div id="centerdiv">
        <div id="detailsmain">
            <asp:HiddenField ID="hidAssetID" runat="server" />
    <!-- Page content -->

    Post schema.org microdata:

    <div id="centerdiv">
        <div id="detailsmain" itemscope itemtype="http://schema.org/Photograph">
            <asp:HiddenField ID="hidAssetID" runat="server" />
    <!-- Page content -->

    The options for validation in my VS are:

    • Internet Explorer 6.0
    • Internet Explorer 3.02 / Netscape Navigator 3.0
    • Netscape Navigator 4.0
    • HTML 4.01
    • XHTML 1.0 Transitional
    • XHTML 1.0 Frameset
    • XHTML 1.1

    I've read that such things can be updated in VS 2010 by adding SP1 - but how do I add them in 2005 ?

    Further from my previous instance of this question (link) I have found out how to install new validation schemas with a bit of a hack:

    Downloaded : http://blogs.msdn.com/b/webdev/archive/2009/11/18/html-5-intellisense-and-validation-schema-for-visual-studio-2008-and-visual-web-developer.aspx

    Instaleld it into the VIsual Studio 9 folder instead of 9, and then re-wrote the REG file to add the key into VS8.0 section and as Schema 21 instead of 23.

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{1B437D20-F8FE-11D2-A6AE-00104BCC7269}\Schemas\Schema 21]
    "Friendly Name"="HTML 5"

    Which adds HTML5 to the list of validation options. However this raises errors of it's own as I am not writing HTML5.

    So where can I get a schema for HTML4 + microdata properties etc ?

    The validation errors in the html editor has no effect on compilation. You can simply ignore the warnings.

    (Also check the xhtml conformance level in the web.config. You need at least transitional.)
