Polyglot markup Polyglot markup In computing, a polyglot markup is a document or script written in a valid form of multiple markup languages, which performs the same output, independent of the markup's parser, layout engine, or interpreter. In general, the "polyglot markup" is a common subset of two or more languages, that can be used as a robust or simplified profile. Polyglot HTML is HTML that has been written to conform to both the HTML and XHTML specifications. A polyglot document can therefore be parsed as either HTML (which is SGML-compatible) or XML, and will produce the same DOM structure either way.

The typeface devised for the Complutensian by Arnaldo Guillén de Brocar has been regarded by typographers such as Robert Proctor as the apex of Greek typographical development in early printing, before Aldus Manutius' manuscript-based typefaces took over the market for the next two centuries. Proctor based his 1903 "Otter Greek" typeface on the Polyglot; the Greek Font Society's "GFS Complutensian Greek" is likewise based on the Polyglot. Complutensian Polyglot Bible The
