Naming restrictions for extensions

PolicyCenter uses the names of extensions as the basis for several other internally-generated structures, such as database elements and Java classes. Because of this, it is important that you adhere to the naming requirements and guidelines described in this section.

An extension name cannot start with a number; it must start with a letter. Other than that, an extension name can contain letters, numbers, or underscores (_). Guidewire does not permit any other characters in extension names.
