In the above example snippet:

1. Lines starting with '[document]' contain the document id.  The document
   id corresponds to the id in the Windows 2000 dataset. The format of 
   such lines is:
     '[document] <document id>'

2. Lines starting with '[sentence]' contain the sentences from the document.
   All word indices (see below) are zero-based indices into this line.

3. Lines containing the tags [textaction], [worldaction], [optional], 
   [command], and optionally [hla] will occur in blocks following a
   [sentence] line.  Each such block specifies the attributes of an
   action performed (or one that should be performed) on the target
   environment, and on the text by the learner being evaluated.
   Each of these tags is described below.

4. Lines starting with '[textaction]' identify the selected word indices,
   and are of the following format:
     '[textaction] [0x01] wc|<command word index>|<command word> [0x01] wu|<object word index>|<object word> [0x01] wp|<parameter word index>|<parameter word>'
   Here '[0x01]' is the hex control character, and a parameter word index
   of -1 indicates that the parameter word is not used by the selected command.

5. Lines starting with '[worldaction]' contain the command, object id, object
   type and object name in the following format:
     "[worldaction] [0x01] c|-1|<environment command> [0x01] u|<object id>|<object name>|<object type> [0x01] <temporally unique object id>"
   The <object id> is guaranteed to be unique only within the current 
   observed world state.  If the same world state is observed again
   at a different point in time, a given object id may refer to a 
   completely different object (The object id is composed of the GUI
   element's Win32 HWND).  The <temporally unique id> attempts to 
   uniquely identify objects across multiple observations of the 
   same state.  While successful in the vast majority of cases, 
   <temporally unique id> is also not always guaranteed to be unique :-/

6. Lines starting with '[command]' specify the actual command that was
   sent to the target environment.  These lines have the following format:
     "[command] <command string>"

7. Lines starting with '[optional]' indicate whether the corresponding
   [command] is optional or not.  A line containing '[optional] [0x01] 1'
   indicates an optional command, and '[optional] [0x01] 0' indicates
   a mandatory command.

8. A line containing the tag '[hla]' indicates that the corresponding
   [command] was produced by a high-level instruction.
