X-Cart forums - 4.4.4 Site Won't Validate

I have modified my Socialize Module to use ShareThis so my visitors have access to over 100 services besides Facebook, Twitter, and Google +1.

With my modification the homepage validates fine with the Socialize module turned on because I've commented out sections and added the ShareThis code as shown below.

I am getting validation errors on the product page related to using the FaceBook Comments part of the Socialize Module and ShareThis. I'll work on Line 97 but I'll live with Line 90 and Line 465.

Line 90, Column 26: there is no attribute "property"
<meta property="og:title" content="xxxxxxxxxxxxxxxxxxxxx...

Line 97, Column 96: general entity "id" not defined and no default entity
Line 97, Column 98: reference to entity "id" for which no system identifier could be generated
┘" content="http://www.mysite-444/image.php?type=T&id=16880" />

Line 465, Column 52: there is no attribute "displayText"
<span class='st_facebook_hcount' displayText='Facebook'></span>

When I finish the mod the way I want my products will list automatically on Twitter and my Facebook Wall. My FB Wall will show thumbnails of the products as well because of the FB code that the x-cart Socialize Module contains.

Access to the other services opens when you hover over the ShareThis icon as shown in the attachment.

Let me know if this is of interest to you and I'll provide more details.

Thanks!
