False parsing error inside href="http://..." !

*** Errors/warnings in [MyFile].html
  line 1969, char 98: not well-formed (invalid token)
But the line is
  <em class="ouvrage"><a 
href="http://studies.d-meeus.be/wikindx3/index.php?action=resourceView&id=401">Dreams 

which is perfectly legitimate (char. 98 is the d of id=). I ask the file 
index.php to view the resource whose id is 401. I cannot but write 
id=401. Amaya should not bother with what I write between the " ".
