| Float | 1.234e+10 | <float>1.234e10</float> |
| Text | quoted only when it contains a comma or a quote | <char>text</char> |
| Long text | must be quoted; line breaks inside force multi-line records | <text>multi-line text</text> (entities for & <) |
| Date | 2026-09-18 | <date>2026-09-18</date> (xs:date with an XSD) |
| Datetime | 2026-09-18 14:30:00 | <datetime>2026-09-18T14:30:00Z</datetime> (xs:dateTime) |

Dialect differences
Both CSV and XML are file formats, so what differs below is how each one chooses to represent a value.
| Property | in CSV | in XML |
|---|---|---|
| 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 |
