Master Page, Custom Content
On page 202 you show how to create a content page based on a Master, where the master has stuff in the ContentPlaceHolderID for the body. Then you say that if you switch the content page to Create Custom Content, "this will ad an empty asp:content control"
It seems to me that what happens is the stuff in the body on the Master actually gets copied into the content page -- it is not blank at all.
What do you think?
