[NTG-context] startMPpage..stopMPpage written to a separate PDF?

I have a series of startMPpage—stopMPpage pairs (with MP code inbetween). These now become separate pages in a single PDF. But I need them to become separate PDF’s each during my ConTeXt run, with a name of my own choosing. Is this possible? I guess this will be problematic, but one can hope

[NTG-context] Puzzle (for me)

I have a string with double quotes that needs to become a text in a box in METAPOST. METAPOST is used to create an image consisting of boxes and connections. Basically, the approach is now something like this: TeX: calls Lua code with \ctxlua{filename} Lua: context.startMPpage Lua: read XML.

[NTG-context] How do I handle strings with " characters in it in METAPOST?

I am using MetaFun (Lua code) to create METAPOST commands from an XML file. One of the issues I am running into that in METAPOST I have to handle strings with " characters in them and METAPOST doesn’t like those. The argument using the string Foo "Bar” Foo turns into someCall( "Foo “Bar”
