 The TeX/LaTeX workflow is deeply embedded into mathematical practice. Therefore the sTeX
-system allows to embed [/structural semantics](/research/structural-semantics) into documents. 
+system allows to embed [/structural semantics](/research/structural-semantics) into
+documents. Concretely sTeX is a "semantic version of LaTeX" that allows to use special
+macros to encode mathematical meaning explicitly. This is (largely ignored in PDF
+generation), but can be taken into account when generating [OMDoc-based](/systems/omdoc/) active documents.
