[NTG-context] How to produce PDF links with custom action?

Hi all! Does ConTeXt allow to create links with custom actions? I have a working LaTeX / PDF-TeX solution which I am not able to port to ConTeXt. The following PDF-TeX code contained in a LaTeX file produces the desired PDF-Code. \\pdfstartlink attr{/Border [ 0 0 0 ]} user{/Subtype/Link/A << /S /AVDP_Action /AVDP_Param (../../nach-dateipfad.pdf 1)>>} here is a link \\pdfendlink Yet, if I include the same lines of code in a ConTeXt file then no link is generated. Thanks for you attention, Stefan
