Functionality
Syntax: changed: <identifier>. The object should have one (and only one) “changed:” attribute with the value <identifier>. <timestamp> will be automatically generated by the DB when the object has been processed.
All other (if any) syntactically correct “changed:” attributes which are in order are preserved. Short form of the <timestamp> (YYYMMDD) is allowed.
Syntax errors:
- Empty “changed:” attribute
- No “changed:” attribute
- Syntactically incorrect “changed:” attribute
