| identifiers | "double quotes" | Attribute values in quotes; entities (& < >) for ... |
| row limit | LIMIT n | — |
| dates | timestamp, timestamptz, date, time | Text (xs:date / xs:dateTime when an XSD is in play) |
| long text | TEXT | — |
| binary | BYTEA | base64Binary / hexBinary inside text |
| separator | — | Tags, not delimiters |
