This package creates a potential privacy breach by fetching W3C validation icons.
These badges may be displayed to tell readers that care has been taken to make a page compliant with W3C standards. Unfortunately, downloading the image from www.w3.org might expose the reader's IP address to potential tracking.
Note that these icons are non-free and must not be copied into the package. You could safely delete this W3C validation badge.
Refer to http://validator.w3.org/docs/help.html#icon and http://www.w3.org/Consortium/Legal/logo-usage-20000308 for details.
