non ottengo la validazione XHTML 1.0 Strict perche' il tag

<a href="#" onClick="MyWindow=window.open('http:www.unsitoqualsiasi.it','MyWindow',' etc etc etc....

non puo' avere l'attributo onClick:

Line 44, column 25: there is no attribute "onClick"


You have used an attribute with an element that is defined not to have that attribute. This is most commonly caused by using vendor-specific attributes without setting the document type appropriately.

Che mi suggerite?

Grazie,

ciao
