[TYPO3-english] ddgoglesitemap and Cal issue

[Tony Lush]

On a site with ddgooglesitemap installed we have a page not in menu that 
displays event details for the Cal calendar extension.

When Google traverses that page it generates an error message, since the 
page is visited without the parameters needed to display any content.

Is there any way to get ddgooglesitemap to not include specific pages so 
we can prevent this error?

Thank you -- Tony
