[NTG-context] two question on ConTeXt terminology

Dear list, I’m writing a document on ConTeXt and I have two questions on terminology. As I have been using LaTeX over a decade, I don’t know whether my descriptions are accurate in ConTeXt. Don’t worry, My questions are extremely basic ;-). What is the name for the part of the document that comes before \starttext? The ConTeXt manual seems to use preamble, but I would like to confirm this use. The other question is more tricky. Or at least I don’t find an obvious answer. Which is the correct expression to name any \start...-\stop....structure? Environment would be the LaTeX term, but this is reserved in ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk
