AN HTML MARKUP QUESTION

Joe Jenett is taking his weblog to the XHTML 1.0 standard and CSS. I use a text editor (not very well) called NoteTab Pro. When I start a new web page, it prompts for the kind of markup I’m doing. In the XHTML choices are:

• XHTML 1.0 Strict
  
• XHTML 1.0 Transitional
  
• XHTML 1.0 Frameset

Which one do I choose to do this XHTML 1.0 thing right? Where’s the place to learn more about what all of this terminology means?
