Each resource info file must begin with the following lines:

The .class key tells the compiler the type of the rbInfo file. The vast majority of rbInfo files are simple message tables, based on the StringResourceInfo class, but other formats also exists. If the .customizable key is set to true, the customer will be able to supply his/her own rbInfo files which will overlay the strings supplied in the default rbInfo files. This mechanism can be used to customize Windchill without modifying the original resource info files. The .deprecated key can be used to put an entire resource info file out of business without actually deleting it from the system. This flag indicates that the content of the file is obsolete and it is not used anymore. Most of the time, you do not have to worry about the header section at all. If you are using .rbInfo files in a non-Windchill environment, these settings are ignored.
