But if there is important information in such comments (title, author, sections, nice names of theorems, important comments, etc.) that will be used for presentation/searching/etc in HTML, FM, MML Query, etc., a parser for these things is needed anyway, so why not re-use the Mizar parser? Also, these things should appear in the XML form of the Mizar article, which is currently produced by the Mizar parser. > More serious problem: what do you mean by 'Inability to present the metadata > in HTML' ? Metadata like title, author, etc. are not present in the XML representation of an article produced by the Mizar parser (because formally they are just ignored comments). Josef
