XML and Yealink IP Phones
1
XML stands for extensible Markup Language. It is a markup language much like HTML.
HTML is designed to display data and to focus on how data looks, while XML is
designed to describe data and to focus on what data is.
XML enables SIP phones to serve as output devices for many exciting applications.
The XML infrastructure allows the phones to interact with external applications in a
flexible and programmable manner.
The following are characteristics of XML:
XML tags are not predefined. You must define your own tags.
XML uses an XML schema to describe the data.
XML with an XML schema is designed to be self-descriptive.
XML is a W3C Standard Recommendation.
