Dialect differences
Both TXT and HTML are file formats, so what differs below is how each one chooses to represent a value.
| Property | in TXT | in HTML |
|---|---|---|
| identifiers | None by convention | Attribute values in quotes; entities for reserved characters |
| dates | Whatever the writer produced; no convention is guaranteed | Whatever text was rendered |
| binary | Not supported | data: URIs inside src attributes |
| separator | Whatever was chosen - often fixed column widths | Tags, not delimiters |
| encoding | No declaration - UTF-8 works only with a BOM | Declared in a meta charset tag or the HTTP header |
| typing | None - every field is text | None |
| shape | Free form; a parser has to be told the layout | Free form; tables are row/column structures inside markup |
