[DFDL-WG] minor spec correction Appendix 33

The tables in Appendix 31 are all going from logical to physical. The case 
you describe only occurs on parsing hence not in the tables.

The behaviour on parsing is defined in 13.2.1 - property escapeKind. The 
escape character is removed from the data unless it is itself escaped.

I'd like to confirm understanding of a particular simple case of escape 
sequences.

Suppose the escape character is "/"

Suppose the delimiter is ";".

If the data stream contains abcd/efgh then does the logical data retain, 
or remove the escape character? (or cause an error?)

This is the case where the escape character isn't escaping anything, so 
the question is whether its special status as escape character is therefor 
ignored, treating it as a constituent character, or it is some sort of 
error we detect.

I was surprised to not find this as row 2 of the table in Section 31.1.

These tables are awesomely useful, but very badly labelled.

Columns Data and Result should be labeled "Logical Data" and "Physical 
Data".
