Xuse manages requirements, use cases & other artefacts that drive software design. Xuse focuses on clear documentation & communication. It defines an XML data model for requirements & use cases with XSLT providing multiple derived views: HTML/SVG/PDF.
Note there is no GUI for entering requirements, however another project (https://sourceforge.net/projects/xguse/) will provide a GUI.
LXD intends to be a documentation system for large OpenSource projects. It mixes low level information (source code symbols) with high level information (modules, abstract data types, algorithms), by using well defined XML documents.
