XOXO (eXtensible Open XHTML Outlines) is an XML microformat for outlines built on top of XHTML. Developed by several authors as an attempt to reuse XHTML building blocks instead of inventing unnecessary new XML elements/attributes, XOXO is based on existing conventions for publishing outlines, lists, and blogrolls on the Web. The XOXO specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data. E.g. the more semantic version of the S5 presentation file format is based upon XOXO.
XBEL, or the XML Bookmark Exchange Language, is an open XML standard for sharing Internet URIs, also known as bookmarks (or favorites in Internet Explorer). An example of XBEL use is the XBELicious application, which stores Del.icio.us bookmarks in XBEL format. The Galeon, Konqueror, Arora and Midori web browsers use XBEL as the format for storing user bookmarks. XBEL was created by the Python XML Special Interest Group [1] "to create an interesting , fun project which was both useful and would demonstrate the Python XML processing software which was being developed at the time," [2].

Stratego/XT is a language and toolset for constructing stand-alone program transformation systems. It combines the Stratego transformation language with the XT toolset of transformation components, providing a framework for constructing stand-alone program transformation systems. The Stratego language is based around a programming paradigm called strategic term rewriting. It provides rewrite rules for expressing basic transformation steps. The application of these rules can be controlled using strategies, a form of subroutines. The XT toolset provides reusable transformation components and declarative languages for deriving new components. Program transformations often operate by modifying the (AST). In Stratego it is also possible to specify transformations using concrete syntax. This allows programmers to express a transformation using the familiar (and often more concise) syntax of the object programming language, while it internally still operates on the AST.
