Answer 1

As part of the publishing features you can add AvailableWebTemplates and AvailablePageLayouts declaratively as feature properties in onet.xml:

<Feature ID="22A9EF51-737B-4ff2-9346-694633FE4416">    <!-- Publishing -->    <Properties xmlns="http://schemas.microsoft.com/sharepoint/">
...
<Property Key="AvailableWebTemplates" Value="*-BLANKINTERNET#1;*-BLANKINTERNET#2"/>
<Property Key="AvailablePageLayouts" Value="~SiteCollection/_catalogs/masterpage/ArticleLeft.aspx:~SiteCollection/_catalogs/masterpage/ArticleLinks.aspx:~SiteCollection/_catalogs/masterpage/ArticleRight.aspx"/>
...
</Properties>
</Feature>

The * can be replaced with a specific LCID (eg 1033) if you only want the template available for specific languages. Seperator is ; for templates and : for page layouts

I would like to know if there is a declarative way to do it. But you can have a feature activtaed which receives following event whenever a new web is being created. You will have an opportunity to check for allowed templates and then redirect the users to error page if needed.

public override void WebAdding(SPWebEventProperties properties) { // Check properties.Web.WebTemplate belongs to the allowed templates... and if not do following

properties.Cancel = true; properties.Status = SPEventReceiverStatus.CancelWithRedirectUrl; properties.RedirectUrl = "/_layouts/Custom/error.aspx"; }
