ah, this seems to explain something else i was looking at.  if i
have the path

  //element[@attr = "value"]

this will obviously select all "element"s with attribute "attr" whose
value is "value".  if i were to write that out the long way, i would
get

  //element[string(@attr) = "value"]

is that right?  that is, using an attribute in a string context
forces it to be converted into its "string-value" value.  ok, 
things are starting to make more sense.
