slight re-arrangement of the examples:

the simple example becomes a cenelec example,
and simple got an example called Article based on
to the LNCS_onto.

+text*[abs::abstract, keyword_list="[]"] {* Isabelle/Isar is a system 
+framework with many similarities to Eclipse; it is mostly known as part of 
+Isabelle/HOL, an interactive theorem proving and code generation
+environment. Recently, an Document Ontology Framework has been
+developed as a plugin in Isabelle/Isar, allowing to do both 
+conventional typesetting \emph{as well} as formal development.
+A particular asset is the possibility to control the links 
+between the formal and informal aspects of a document
+via (a novel use of) Isabelle's antiquotation mechanism.
