  No.  When called without an argument, the context node is converted to a 
string and used as the argument.  There are many alternative ways to test 
whether the string value of the context node is the empty string, I simply 
carried the one that the OP used so as not to confuse the reference.  Other 
possibilities include
string(.) = ''
normalize-space() = ''
normalize-space(.) = ''
not(string(.))
normalize-space(string-length(.)) = 0
etc.

  Wendell posted "not(string())", but according to topxml.com (I know, 
it's not the canonical source), a call to string() with no arguments always 
returns the empty string.  I haven't verified that one either way...

  I left it out in case the calling template would care to modify 
attributes of 'td' such as rowspan or width.  Personal choice, I guess.
