Hi,
A couple of years ago, I decided to switch from LaTex to ConText. Now
I have compiled a lot of documents (Physics syllabi's) which compiles fine
in MK-II.

I thought I would try to make a switch to MK-IV, mainly because I
want to include 3D PRC figures in my documents.

I made some test cases to test MK-IV in order to get a handle on the differences between MK-II and MK-IV

Some of my observations are
*) Numbered formulas, numbered by section, don't seem to work
*) I am getting a lot of warnings of identifiers, apparently used more than once, which they are not
LuaTeX warning (ext4): destination with the same identifier (name{km1_chapter1_sec1}) has been already used, duplicate ignored

Question
Are these observations correct, someone else can confirm them ?
Question
If so, is there a fix, patch, or change in ConText commands/options I am not aware of ?

TIA
