It's handled in vile by interpreting control sequences
There are a couple of sections in the help-file that discusses the control
sequences:

  Attribute control sequences (ACS)
  Writing your own filters
  Hypertext

in particular this comment:

   The <command> for hypertext commands may be any sequence of characters
   except for newlines and null characters. A null character must terminate
   the hypertext command. The command should be a valid vile command such as
   you might enter into your .vilerc file.

It's not an html file (though with some work, one could write a filter
say for lynx that would produce a file that could be read into vile and
act like that).
