* A datum of any other type is either a scalar of that type (if
* ca_len is zero), or an array of ca_len elements of that type.

+ * obtained by calling ca_get(VAL, NP, CTXO), where VAL has been

+ * NP points to the country to use for coordinate translation and

+ * See struct valstr for details.
+ * Because virtual selectors don't have a setter method, xundump must

* If flag NSC_DEITY is set, only to deities can use this selector.
- * If flag NSC_EXTRA is set, xdump ignores this selector.
+ * If flag NSC_EXTRA is set, xdump and xundump ignore this selector.
* If flag NSC_CONST is set, the datum can't be changed from its
* initial value (xundump obeys that).
* If ca_table is not EF_BAD, the datum refers to that Empire table;
