It is probably a good idea to avoid using [ and ] as version 4 will have array support and these will have a special meaning in the names. Also "." is the delineation between name and field - and with version 4 support for structures, this will be the delimitor between structure and strucutre elements.
Marty should comment is this is not correct.

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.
