Lintian tag information: privacy-breach-w3c-valid-html (type: error)

Description (from lintian-explain-tags)

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.

Please refer to http://validator.w3.org/docs/help.html#icon and
http://www.w3.org/Consortium/Legal/logo-usage-20000308 for details.
