I currently have a document in which there are numerous tables each  
with local footnotes marked by alphabetic characters. When I process  
the file, I get complaints like:

pdfTeX warning (ext4): destination with the same identifier (name{a})  
has been

                    \egroup

l.354 \footnotetext[a]
                       {See \goto{Pingree 1977}[Pingree1977].}

Is there a way to reset the localfootnote counter so that ConTeXt is  
happy and the footnotes marked by arabic numerals are undisturbed.  
Something like \resetnumber[localfootnotes] perhaps, though this does  
not work.
