- library/lib/doc-tools.tcl: Some fixes, including adjusting @class.inherited() to return only doc entities of classes which are part of the same project as the inheritee. - library/lib/doc-tools.tcl: Integrated an xodoc-compat infrastructure and provided for processing xodoc packages (see processor.process=@package()). - tests/doc.test: Now also serves a nxdoc port of the XOTcl-langref package - library/xotcl/doc/langRef.xotcl: equipped with an empty namespace declaration (to please pkg_mkIndex.tcl) and import ::xotcl::@ by default (for convenience).
