Here's the relevant section from the Application Developer's Guide:

6.3.2 Unquoted Strings
In the summary section, some values are shown as quoted strings and some 
unquoted. The actual rule is that any string
consisting of only the following characters does not have to be quoted:
a-z A-Z 0-9 _ - : . [ ] < > ;
These are also the legal characters for process variable names. Thus in many 
cases quotes are not needed.
