Parsing Error with Amaya 5.1

Hi,

I'm editing old HTML pages built with Amaya V4.3. The 5.1 version gives
me a parsing error due to the link tag :

<link rel="stylesheet" type="text/css" href="index.css">

*** Errors/warnings in /home/alex/dev/tvi/doc/tutorial/udb/page3.htm
line 11, char 2: mismatched tag
