This is a top level element in every HTML document which encapsulates information
and directions in an unordered fashion that are ABOUT the HTML
document. No actual document content is located in the HEAD element.
This attribute specifies the location of one or more white-space
separated meta data profile URLs for the current document. Such profile
URLs would allow for rich classes of information about the current document,
in much the same way as the META element.
[Either an absolute or relative URL. All URLs should be URL encoded where required.]
is a title</title>
Although it is not required to have this element in HTML documents (XHTML
DOES require it), it is still a basic top level element in the HTML
document structure and it is considered bad style to omit it. Having it
present more clearly defines the boundaries between HEAD and BODY elements
for a parser or person reading the HTML code.
