Nit: 10.2.2.2 refers to type by otherwise unmentioned CamelCaps name

[Jim Blandy]

In section 10.2.2.2, algorithm step 2 refers to the declarative 
environment record type by the StUdLyCaPs name 
DeclarativeEnvironmentRecord, which is never defined or used elsewhere.  
Perhaps it should simply be "declarative environment record", as used 
elsewhere in the section.
