Full capitalisation of normal words, underlining, boldface and scare quotes must be limited to one phrase in any two consecutive paragraphs, or two words in any two, three in three, etc. up to a limit where the use of n so emphasised words in m paragraphs, n>m, requires n-m paragraphs either side to be free of such emphasis, and thus requires the document to contain at least n paragraphs, excluding headers.
Any statutory requirement for whole paragraph emphasis must be provided by a margin stripe.
A new version of a document must clearly indicate through appropriate colours where text has been added, changed or deleted, with the old version made visible by hovering over the change indicator.
A timeline slider must be provided to give access to diffs against earlier versions (which the user has accepted).
The user's acceptance on one device must be recognised as acceptance for all devices linked to that account.
The user must be asked to separately indicate acceptance of each significant change.
A button must be provided to allow a user to view or "print" the document in traditional style, i.e. with full capitalisation of parts to be glossed over.
A button must be provided to number the paragraphs with nesting and other supplementation to avoid cascading number changes between versions.
Default full word text is to be no smaller than 11 on 13 and all sub and superscripts no smaller than 8 point, with standard interface options to zoom in or out.
Installers must enforce compliance with these guidelines.
