Preferences

For object identifiers the char preferences are given by the following order:

char as regex	note
a-zA-Z
0-9
_ if a space shall be presented
-	to increase readability, e.g. in ISO 8601 data representation
/	to mark directories
.	to be used instead of / , e.g. in file names

In path names the "/" is used. If "/" cannot be used the general recommendation is to use the "." instead.
