XML file
From TrillWiki
XML stands for Extensible Markup Language
XML is a specification defined by the World Wide Web Consortium (W3C), the same group that gave us the HTML and PNG image specifications. (As well as SVG, but that's another story.)
As defined in the W3C XML Spec:
- [XML] partially describes the behavior of computer programs[...]
- XML documents are made up of storage units called entities, which contain either parsed or unparsed data. Parsed data is made up of characters, some of which form character data, and some of which form markup. Markup encodes a description of the document's storage layout and logical structure. XML provides a mechanism to impose constraints on the storage layout and logical structure.
Essentially what that means (for the sake of this reference) is that XML made up of text files that are designed to control how a program displays data. In the case of our favorite IM client, Trillian's SkinXML defines how Trillian's windows look.
