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?
Often, the header of a document contains a number of <meta> tags used to convey
additional information about the document to the browser. In the future, authors
may use predefined profiles of standard document metadata to better describe their
documents. The profile attribute supplies the URL of the profile associated with the
current document.
The format of a profile and how a browser might use it are not yet defined; this attribute is primarily a placeholder for future development.
