[NTG-context] using both footnotes and endnotes in a document

A puzzle for note specialists: I would like to use both endnotes as well as footnotes in one and the same document, for different kinds of notes. Ideally, I should be able to write something like: ----- Here is a footnote,\footnote{The footnotes comes here.} and now comes an note that should appear at the end of my text.\endnote{And this is the endnote.} ----- For this I would need commands for determining the kind of markers for the notes (I know what to do for footnotes: this looks like \setupfootnotes [conversion=characters]; but what does one do for endnotes?)
