  TECHDOC is an implemented system demonstrating the feasibility of generating
multilingual technical documents on the basis of a language-independent
knowledge base. Its application domain is user and maintenance instructions,
which are produced from underlying plan structures representing the activities,
the participating objects with their properties, relations, and so on. This
paper gives a brief outline of the system architecture and discusses some
recent developments in the project: the addition of actual event simulation in
the KB, steps towards a document authoring tool, and a multimodal user
interface. (slightly corrected version of a paper to appear in: COLING 94,
