schemas in OPPID SS5

After reading through some of the posts on schemas I am finding there are quite a few that are beneficial to our process, but in trying to change things I am finding that my schemas are named different than the ones that are presented in the posts.  For example OpenPlant_.01.04.eschema as mentioned in other posts is showing up in my files as OpenPlant_PID.01.04.eschema, therefore the supplemental schema is only giving me the option to load PID_Supplemental.  Has there been changes made in naming of schemas throughout the revision process or possibly if I add PID to the schema name will it recognize it?
