identifiers	`Double quotes; a literal quote is doubled ("" )`	`Attribute values in quotes; entities (& < >) for ...`
dates	`Conventional text: 2026-09-18 or 2026-09-18 14:30:00`	`Text (xs:date / xs:dateTime when an XSD is in play)`
binary	`Not supported`	`base64Binary / hexBinary inside text`
separator	`Comma ","`	`Tags, not delimiters`
encoding	`No declaration - UTF-8 works only with a BOM`	`Declared in the XML declaration`
typing	`None - every field is text`	`None in the markup itself`
shape	`Flat table, optional header row`	`Arbitrary tree`
ceiling	`No formal limit; row count bounded by memory`	`Whole document is usually parsed into memory`
