| identifiers | "double quotes" | Attribute values in quotes; entities (& < >) for ... |
| row limit | FETCH FIRST n ROWS ONLY | — |
| dates | DATE, TIMESTAMP | Text (xs:date / xs:dateTime when an XSD is in play) |
| long text | CLOB, NCLOB | — |
| binary | BLOB, BFILE | base64Binary / hexBinary inside text |
| separator | — | Tags, not delimiters |
| encoding | — | Declared in the XML declaration |
| typing | — | None in the markup itself |
| shape | Tables of rows and columns | Arbitrary tree |
