The HTML mirrors in LAML

LAML - slide 9 : 24

A HTML mirror in Scheme is a set of functions that in an accurate way makes the HTML elements of a particular HTML version available in Scheme

A one-to-one mapping of HTML elements to named functions in Scheme
Generates well-formed and valid HTML documents
Prevents accidental emission of '<', '>', and '&' as part of the textual contents
The mirror functions return abstract syntax trees which can be rendered as 'HTML text'
Supports optional pretty printing of the resulting HTML code

Not too many functions - not too few. You cannot by accident use a non-standard HTML element
