Number of Links and Nesting

Hi,

I have a couple of questions regarding XLink technology.

1. Is there a limit on the number of links that an XML document can contain?
2. Can nesting of links occur and if so is there a limit on the nesting
level?
3. Is it OK have multiple links to the same resource?

Thanks
