[NTG-context] keep section head with following paragraphs

Hi Again, Thanks for taking the time with my questions. ConTeXt is letting me set up some very cool newsletter type documents. I have it rigged up with DocBook using XSL to transform XML to ConTeXt. much fun! my question: how do i make sure that section heads will not be alone at the bottom of the page, with the following paragraphs at the start of the next page? i want the section head to stay with the first paragraph (or at least the first two lines) of the paragraph immediately following the section head. thanks, mark
