Custom xmlsitemapprovider can't set Title of sitemapnode?

Question

I created my custom XmlSiteMapProvider. Works out great but I want to be able to change the Title of the SiteMap also in there. However I get exceptions that Title is suddenly readonly while the property has a setter when viewing in the Object Browser. Anyone can explain this behavior?

I've been trying to create a new node, use the RemoveNode method to delete the current one and then use the AddNode method. However when I use the method with 1 parameter it starts to complain (exception that the parentNode can't be null). If I use the method overload with 2 parameters and want to pass in the parentNode of the node to delete it's also null. How to solve this?

Apparently it's not possible due to optimizations by Microsoft. The base class to be used instead is StaticSiteMapProvider.
