[O] HTML export with ":export" parameter with Orgmode 9.0

[Frederick Giasson]

Hi,

I am not clear about the change in the Export blocks that occurred in 
Org-mode 9.0


Does this change impact the ":export [...]" code block header parameter? 
What I am often using is this:


    http://orgmode.org/manual/Exporting-code-blocks.html


Which currently doesn't work but it is unclear from the release notes if 
it should or not and the code provided to fix the Export blocks doesn't 
appear to look for this syntax, so I guess it should still be working.


Anybody else experience this issue?


Thanks,


Fred
