 \subsection{Uses}
 \begin{description}
   \item[ocg] old sty, only pdftex. Add something to Properties, takes care of the rest of the resources but not of the current content of Properties.
-  \item[colorspace] Add entries to the Colorspace dict. Seems to expect that color are defined in the preamble or the first page. Unclear if it still clashes with pgf, see https://tex.stackexchange.com/a/405166/2388.
-  \item[hyperref] adds /OCView and /OCPrint to Properties, takes care of other content of pdfpageresources, but not of the content of Properties.
+  \item[colorspace] Add entries to the Colorspace dict and also /ExtGState. Seems to expect that color are defined in the preamble or the first page. Unclear if it still clashes with pgf, see https://tex.stackexchange.com/a/405166/2388. Additions to ColorSpace are page wise!
+  \item[hyperref] adds /OCView and /OCPrint to Properties, takes care of other content of pdfpageresources, but not of the content of Properties. (experimental driver uses central interface).
   \item[pdfbase] adds content to Properties, takes care of other content of pdfpageresources, but imho not of the content of Properties. Will probably have a problem if the value of Properties is an indirect object.
-  \item[transparent] adds content to ExtGState \verb+/ExtGState<</TRP1<</ca 1/CA 1>>>>+. Tries to be compatible with pgf.

 \subsection{Discussion}
 Every of the five dictionaries ExtGState, ColorSpace, Pattern, Shading, Properties can receive values from more than one package and must combine them. So every of this entries needs its own properties and commands to add to the property. Packages can avoid duplicate keys by suitable name spaces.
 
+At least two should be handled pagewise.
 It must be decided when to write the properties to pdfpageresources.
