Permit special Boolean syntax not only with EBoolean (which is mapped to
boolean primitive type) but also with EBooleanObject (which is mapped to
java.lang.Boolean).
Added support for multi line comments to .cs files.
Added new file content creation that uses the namespace URI and the name
of the start class from a genmodel with similar name to the newly
created .cs file if it exists and synthesizes a tentative file
extension.
Added a new class XyzStringParser to be generated with the resource
project, which allows easy parsing of plain string representations of
artifacts in the concrete textual syntax. Thanks to jreimone for the
hint.
Modified generation of the XyzAutoEditStrategy to more closely resemble
the procedure known from Eclipse editors:

a) A closing bracket/quote is only inserted automatically if it closes a
yet open bracket/quote pair (e.g., relevant for quoted strings when
manually typing the second quote where now no additional excess quote is
added).

b) When typing a closing bracket/quote manually and the following
character is the very same symbol, then the following symbol is replaced
instead of adding an additional excess closing bracket/quote. Increases
typing flow when manually typing the same content as was previously
generated automatically.

Fixed a few minor bugs in the process.
