ML Pure: name spaces have been refined; ML Pure: cases produced by proof methods specify options, NONE means to removee bindings;

moved is_ident to General/symbol.ML;

Theory.restore_naming; tuned fold;

make: T option -- actually remove undefined cases; Logic.nth_prem; tuned;

renamed cond_extern to extern; support general naming context; added qualified_names, no_base_names, custom_accesses, restore_naming; removed qualified, restore_qualified; add_cases: RuleCases.T option; put_thms etc.: back to simple form, use naming context for extended functionality;

method_cases: RuleCases.T option; goal cases: remove previous ones; invoke_case: ProofContext.no_base_names o ProofContext.qualified_names; undefined rule_context: remove instead of empty one; tuned;

renamed cond_extern to extern; Sign.declare_name replaces NameSpace.extend; (RAW_)METHOD_CASES: RuleCases.T option;

renamed cond_extern to extern; Sign.declare_name replaces NameSpace.extend; proper use of naming context; tuned rename_facts; note_thmss_registrations: avoid non-linear use of thy (via sign);

improved naming of complex theorems in presentation;

added short_names, unique_names options;

renamed cond_extern to extern; Sign.declare_name replaces NameSpace.extend;

added symbol scanner;

remove(_multi): generalized type;

added is_ident (from Syntax/lexicon.ML);

renamed cond_extern to extern; append, base, drop_base, map_base: made robust against empty names; added qualified; extern: improved output for non-unique non-hidden names; name entry path superceded by general naming context; added reject_qualified, default_naming, add_path, no_base_names, custom_accesses, set_policy;
