Thanks, Aditya.  However, I'm don't think that \setupfloat[figure][default=here,top,bottom,page] addresses my need for float pages.  If you compile the document below, you'll notice that the figures at the end of the first section are floated throughout sections 2-4.  I would like the rendering of the floats to catch up by placing the floats on float pages, before moving on to other text.  Is this possible in ConTeXt?
