Workaround(s)
Attribute/Element/UserData extensions are a really useful mechanism to store custom app data into the mesh.

However, the ability to query them is a must.

While querying attribute extensions, for example, we're getting an exception that method calls are not allowed (where a typical query would be Where(r => r.AttributeExtensions.Any(a => ... ))). Same goes for element extensions and user data.

Am I missing something in the query API? Is this something that will be added?
