Which W3 standards does Netscape 7 adhere to ?

To Whom It May Concern: 
I have a list of all the Elements and corresponding Attribute lists which the W3C makes standard (or says to support) under the HTML 4.01 specification. I have included 2 elements (A & ACRONYM) as examples. From this complete list published by the W3C, I would like to know which tags are NOT supported by Netscape Navigator 7. Please note that in the example below I have managed to find out some of these tags which are not supported by Netscape Nav 7. Can anyone help with this arduous task? Or at least direct me to an organization/webpage/or document which might have such useful information. I truly appreciate all input and your efforts.
