When importing data from Toolbox into Lexus we have not forget about the following.
(1) Remember that not all markers are used in every entry and it would be a waste of time to list all the unnecessary markers just for the sake of keeping to the hierarchy. LEXUS reads only the markers that are used in a particular entry, and makes a structure out of them according to the .typ file.
(2) LEXUS does not see, it does not include. That is to say, it is not enough for a marker to appear in an entry for LEXUS to read it. It also has to have a value to be recognised by LEXUS. Whenever you have a marker that has no value this marker will be simply omitted. In some cases, however, this can work to your advantage, becaause LEXUS will always create a coherent minimal structure out of the lexical entry according to the given .typ pattern. Therefore, an empty marker can never lead to the afore-mentioned complications. Do not forget, however, that too many nameless markers can lead to problems addressed in section 2.2 above.
In case you encounter problems, you can contact the LEXUS technical group at: firstname.lastname@example.org.
