How to add a new attribute (without WOK): 
-----------------------------------------

This works only for simple types (ex: string)

example: add attribute FileType (string)

# new files (copied from files specific to ExternalFileDef attribute = string):

? src/SALOMEDS/Handle_SALOMEDS_FileType.hxx      <---  Handle_SALOMEDS_ExternalFileDef.hxx
? src/SALOMEDS/SALOMEDS_AttributeFileType_i.cxx  <---  SALOMEDS_AttributeExternalFileDef_i.cxx
? src/SALOMEDS/SALOMEDS_AttributeFileType_i.hxx  <---  SALOMEDS_AttributeExternalFileDef_i.hxx
? src/SALOMEDS/SALOMEDS_FileType.cdl             <---  SALOMEDS_ExternalFileDef.cdl
? src/SALOMEDS/SALOMEDS_FileType.cxx             <---  SALOMEDS_ExternalFileDef.cxx
? src/SALOMEDS/SALOMEDS_FileType.hxx             <---  SALOMEDS_ExternalFileDef.hxx
? src/SALOMEDS/SALOMEDS_FileType.ixx             <---  SALOMEDS_ExternalFileDef.ixx
? src/SALOMEDS/SALOMEDS_FileType.jxx             <---  SALOMEDS_ExternalFileDef.jxx

# files modified:

M idl/SALOMEDS_Attributes.idl
M src/SALOMEDS/Makefile.in
M src/SALOMEDS/SALOMEDS_SObject_i.cxx
M src/SALOMEDS/SALOMEDS_StudyBuilder_i.cxx

# detailled modifications:

- in new files,
change ExternalFileDef in FileType everywhere
- in SALOMEDS_FileType.cxx,
Standard_GUID (Global Universal IDentifier) must be changed.
To obtain a new GUID, it is possible to use guidgen.exe on windows (with visual C++).

- in src/SALOMEDS/Makefile.in,
add under LIB_SRC = \
		  SALOMEDS_FileType.cxx \
	          SALOMEDS_AttributeExternalFileDef_i.cxx \

- in src/SALOMEDS/SALOMEDS_SObject_i.cxx,
- in src/SALOMEDS/SALOMEDS_StudyBuilder_i.cxx,
- in idl/SALOMEDS_Attributes.idl,
find portions of code containing ExternalFileDef, duplicate and replace
