My concern deals with this passage:

To remain in compliance with the GSL, you may not
reproduce any running text, statistics block, or table from
the Core Rulebooks, nor may you define, redefine, or alter
the definition of any 4E Reference. Nothing in these
guidelines should be taken as contrary to these GSL
requirements.

I am not one for legalese but does this mean they are prohibiting you from modifying any named class in the SRD (like Cleric) or race (like elf). Meaning you have to use their elf and could not make your own. Later there is this passage:

While you may not reproduce running text and tables from
the Core Rulebooks, you may create original material that
reflects the influence of rules and guidelines in the Core
Rulebooks.
For instance, you may create powers that resemble
those in D&D 4E Player’s Handbook.

This seems to indicate you could. If the first passage is to be taken as gospel, I must follow it with another questions: Can you simply delete? Can you create a setting where you say, "No Clerics" or must the entire SRD apply? I hope someone can help us with this.
