•Is XUL
a standard? No. It’s an XML application Netscape invented. (Plan to submit for
standardization in the future.)
•Does
XUL duplicate or compete with web standards? No. It answers a question no
web standard
now does: “How can you define a desktop application UI using
standards?”
•XUL
uses XML as it was intended—as a way to define new markup languages (XML applications) for
specific purposes.
