Tidy Tag Table

Preamble

This started with issue (PR) #848, which, in essence, is the addition of the slot tag in 'libTidy', a good, important aim...

Some of this disccussion gets into how to 'define' this NEW tag, slot, in the 'libTidy' def_tags table definitions. It seems the current PR choice of 'ParseInline', with only a 'CM_INLINE' flag... is a question... or at least other options/flags be tested, considered, ... but in the end, maybe this is indeed the best choice for 'libTidy'...

It seems the choice may be related to the definition of Phrasing content, and Flow Content... The tag slot is present in BOTH... for a quick comparison, these online pages have been roughly added below Phrasing and Flow.

But 'libTidy' has NO definition of 'Phrasing content' or 'Flow content', but uses the tag 'parser', and 'flags', to achieve maybe the same aim...

Maybe a study on the current C table, in libtidy, will yield some clues...

It is obviously better to view this list online, where there are 'links' to each element, which may give further insight... and read the latest, since this is a Living Standard, thus subject to change, but this is a quick, rough, flat list for comparison purposes only.

3.2.5.2.2 Flow content

Most elements that are used in the body of documents and applications are categorized as flow content.

a, abbr, address, area (if it is a descendant of a map element), article, aside, audio, b, bdi, bdo, blockquote, br, button, canvas, cite, code, data, datalist, del, details, dfn, dialog, div, dl, em, embed, fieldset, figure, footer, form, h1, h2, h3, h4, h5, h6, header, hgroup, hr, i, iframe, img, input, ins, kbd, label, link (if it is allowed in the body ), main (if it is a hierarchically correct main element ), map, mark, MathML math, menu, meta (if the itemprop attribute is present), meter, nav, noscript, object, ol, output, p, picture, pre, progress, q, ruby, s, samp, script, section, select, slot, small, span, strong, sub, sup, SVG svg, table, template, textarea, time, u, ul, var, video, wbr, autonomous custom elements, text

3.2.5.2.5 Phrasing content

Phrasing content is the text of the document, as well as elements that mark up that text at the intra-paragraph level. Runs of phrasing content form paragraphs.

a abbr area (if it is a descendant of a map element) audio bbdi bdo br button canvas cite code data datalist del dfn em embed iiframe img input ins kbd label link (if it is allowed in the body )map mark MathML math meta (if the itemprop attribute is present) meter noscript object output picture progress qruby ssamp script select slot small span strong sub sup SVG svg template textarea time uvar video wbr autonomous custom elements text

Conclusions - to be done

But it seems there are no conclusion to be drawn
