Semantic, Extensible, Computational, Styled, Tagged (SECST) markup provides a new way to rapidly create technical guides, training materials, and other interactive documents with far more expressive power than Markdown and less complexity than HTML. No jumping through hoops, no drudgery, just joy!
Introduction
Markdown is a great, well established means of rapidly creating documents with a moderate amount of formatting for web delivery. Over the years (it was first created in 2004) more and more features have been added to the language. However, due to its non-uniform approach to formatting instructions, it is reaching the limits of possibility for expressive power without resorting to inline HTML. HTML is verbose and makes documents hard to read in raw form. And, neither Markdown or HTML have intrinsic navigational support for large documents. Yet, conventional word processors such and MS Word and Google Docs that provide the expressive power authors often seek, fail to produce portable and accessible web content. And, platforms like Jupyter which meets the needs of many data scientists are hamstrung by the limits of Markdown while also requiring special hosting.
