How about a hash attribute for all elements that link to external files
(a, img, etc.)?
It would allow you to pass an MD5, SHA-1, SHA-256, or other hash to a
user-agent for automatic comparison with the linked file.
A related proposal is:
http://www.gerv.net/security/link-fingerprints/
That proposal has the advantage that the hash can accompany the URL into
non-HTML contexts.
I'd suggest a format where the hash algorithm is listed, followed by a
forward slash and then the hash itself
To ease the implementation and interoperability burden, the smallest
possible number of hash functions should be required to be supported.
