Dialect differences

Both HTML and TSV are file formats, so what differs below is how each one chooses to represent a value.

Property	in HTML	in TSV
identifiers	`Attribute values in quotes; entities for reserved characters`	`Rarely used, which is exactly why tabs in data break it`
dates	`Whatever text was rendered`	`Conventional text: 2026-09-18 or 2026-09-18 14:30:00`
binary	`data: URIs inside src attributes`	`Not supported - must be encoded`
separator	`Tags, not delimiters`	`Tab`
encoding	`Declared in a meta charset tag or the HTTP header`	`No declaration - UTF-8 works only with a BOM`
typing	`None`	`None - every field is text`
shape	`Free form; tables are row/column structures inside markup`	`Flat table, optional header row`
