Parsoid/Internals/data-parsoid

Temporarily in data-parsoid, but not in final DOM output
tsr: Tag widths for all tokens (from tokenizer)

extTagWidths: Width of opening and closing tags for extension tags. Ex: ,

Proposal: Make these temporary properties used till we lint the HTML (instead of emitting to final DOM output)
autoInsertedStart: whether this start HTML tag has no corresponding wikitext and was auto-inserted to generated well-formed html. Usually happens when treebuilder fixes up badly nested HTML.

autoInsertedEnd: whether this end HTML tag has no corresponding wikitext and was auto-inserted to generated well-formed html. Ex:, , , , etc. that have no explicit closing markup. Or, html tags that aren't closed

Proposal: Remove from data-parsoid and rely on selser to preserve syntax variations
selfClose: are void tags self-closed? (ex: vs )

noClose: void tags that are not self-closed (ex:  )

brokenHTMLTag: used to RT back these kind of tags: or  or 

srcTagName: source tag name (records case variations) for HTML tags. Ex: vs  vs 

startTagSrc, endTagSrc, attrSepSrc: source for start/end/attribute-text separators (used in table wikitext) pipetrick: true if the link was a pipetrick Foo (NOTE: This will likely be removed soon since this should not show up in saved wikitext since this is a pre-save transformation trick.)
 * |foo || bar
 * |foo || bar
 * | foo
 * |style='color:red;' | foo || bar

Proposal: Maybe move to data-mw?
stx_v: "row"  set for td/th cells that show up on the same line. Ex: |foo ||bar ||baz (Maybe use stx: for this as well)

stx:
 * "html" - set for html tags. Ex: foo
 * "row" - set for dt/dd that show on the same line. Ex: ";a:b" vs ";a\n:b"
 * "piped" - set for piped wikilinks with explicit content Ex: bar vs Foo
 * "magiclink"- set for magic links (RFC/PMID/ISBN) Ex: RFC 1234, ISBN 1234567890 (Not needed anymore?)
 * "url" - set for url links Ex: http://google.com (Not needed anymore?)

Required properties
dsr: Wikitext source ranges that generated this DOM node (start-offset, end-offset, start-tag-width, end-tag-width).

Consider input wikitext:. Let us look at the  part of the input. It generates. The dsr property of the data-parsoid attribute of this i-tag tesll us the following. This HTML node maps to input wikitext substring. The opening tag  was 2 characters wide in wikitext and the closing tag   was also 2 characters wide in wikitext.

src: used to emit original wikitext in some scenarios (entities, placeholder spans)
