Prefix Id's Indesign and PluginDependency

I'm using these ranges of prefixes {0xe9500, 0xe9550, 0xe9600, 0xe9700, 0xe9800} {0xe9500} based on that was generated when you create a plug-in by dolly. With these ranges plug-ings generated not give me problems with PluginDependency. I asked a prefix through the support page http://partners.adobe.com/public/developer/indesign/register/prefix_reg.do

and have given me this 0x1bba00, I think the ranges are 255 (0xFF) when used for a plug-in the {0x1bba00} and {0x1bba50 for another plug-in according to the above, when starting Indesign tells me not to load the first plug-in because it lacks the second, ie it is as if not recognize those prefixes.

My question is, as you have to ask prefixes and use them when you have plug-ins dependent on others?
