+Dynamically built family naming policy
+------------------------------------------
+
+Regarding the :ref:`dynamically built families <dynfam>` the file naming policy is slightly different.
+ASCII letters, numbers and the `"_"` (undescore) character are allowed, that is we allow uppercase characters.
+
+Why allowing uppercase letters for a dynamic familly? 
+Because we have choosed to write :term:`identifiers <identifier>` in uppercase.
+
+.. note:: The identifier is in uppercase, but the dynamic familly name is in lowercase. 
+          You can then choose the corresponding structure filenames in lowercase.
+
+.. seealso:: For more information about dynamic famillies, please have a look at the
