The XML Version of the TEI Guidelines<null> |
| <null> | (Null value) represents the null set, bag, or list, depending on whether the org attribute of its parent <f> has the value set, bag, or list; has no interpretation if the org attribute of its parent <f> element has the value single. | |
| Attributes | Global attributes and those inherited from featureVal | |
| Example |
<f name="empty" org="list"><null/></f> |
|
| Note |
If the <null> element occurs as the value of a feature, it must be the only value. It is also a semantic error for the org attribute of that feature to have the value single. |
