What is the use of profile attributes in the HTML <head>
tag?
I happened to read about it in here : http://www.w3schools.com/tags/tag_head.asp.
I could not understand this(http://www.w3.org/2002/12/namespace) either, since it is too technical (for me).
I have never used it. What is the purpose it serves?
The URI in the profile attribute points to a document containing information regarding metadata. Profiles defines properties that may be used by the HTML meta tag
and the HTML link tag
. There are no prescribed formats for profiles. The profile attribute is no longer supported in HTML 5.
