XML is language independent

By being language independent, XML bypasses the requirement to have a standard binary encoding or storage format. Language independence also fosters immense interoperability amongst heterogeneous systems. It is also good for future compatilbilty. For example, if in the future a product needs to be changed in order to deal with a new computing paradigm or network protocol, by keeping XML flowing through the system, addition of a new layer to deal with this change is feasible.

DOM and SAX are open, language-independent set of interfaces

By defining a set of programming language independent interfaces that allow the accessing and mutation of XML documents, the W3C made it easier for programmers to deal with XML. Not only does XML address the need for a standard information encoding and storage format, it also allows programmers a standard way to use that information. SAX is a very low level API, but it is more than what has been available before it. DOM is a higher level API that even provides a default object model for all XML documents (saving time in creating one from scratch if you are using data is document data).

of the web-server directory, which is some subdirectory of the server's local file system.  For security reasons, browsers can't access stuff outside the web-server directory. 

URLs can specify files by  relative or absolute path.  A relative URL specifies a file relative to the location of the file containing the URL.  An absolute URL specifies the full server name and path from the root directory of the web-server.  Suppose your web page is and it includes a link to cadavers.html which is located in the same subdirectory.  The link could specify the relative URL <A HREF="cadavers.html"> styles would be removed from the former and applied to the latter. This is a welcome capability, as it reduces the need for using JavaScript to create such effects.


There are serious issues related to document reflow with :hover and :focus. Take, for example:

A:hover {font-size: 200%;}
