[whatwg] Link rot is not dangerous

[Kristof Zelechovski]

While searching the Web for "dc" may not be that helpful, you can always
search for "dc:creator".  The incompatibilities of Dublin Core versions
should never happen; once you publish an interface, you should not change
what it means and how it works.  Microsoft solves this problem by appending
version numbers to names.
That said, the author is free to use foaf: for Dublin Core or dc: for FOAF
if he likes, so in this case Web search will fail.  And there is no
guarantee that the reader will not try to find out the semantic using Web
search of the property name instead of dereferencing the CURIE.
