XML
Short for eXtensible Markup Language, a new specification being developed by the
W3C. XML is a pared-down version of SGML, designed especially for web documents.
It enables designers to create their own customized tags to provide
functionality not available with HTML. For example, XML supports links that
point to multiple documents, as opposed to HTML links, which can reference just
one destination each.
XPFE
(Cross Platform Front End) A suite of technologies used to create applications
that will work and look the same on different computer operating systems. A
widely used XPFE application is the Netscape web browser in version 7 and later.
The primary technologies used in creating XPFE applications are Javascript,
Cascading Style Sheets, and XUL.
X Modem
A file transfer protocol. Rather slow.
XML Processor
A program that can XML documents and access their content.
XUL
(eXtensible User-interface Language) A markup language similar to HTML and based
on XML. XUL used to define what the user interface will look like for a
particular piece of software. XUL is used to define what buttons, scrollbars,
text boxes, and other user-interface items will appear, but it is not used to
define how those item will look (e.g. what color they are). The most widely used
example of XUL use is probably in theMozilla web browser, where the entire user
interface is defined using the XUL language.
