应该将[attribute]令牌从[全局属性]更改为[attributes]，而无需命名空间

Question

这个问题与Irony项目的C＃语法示例有关。
原始语法位于此处：CSharpGrammar.cs。

这是我修改后的C＃语法，但应将[attribute]非终结符从[全局属性]更改为[attributes]，而无需命名空间。

怎么办？

this.Root = compilation_unit;
compilation_unit.Rule = extern_alias_directives_opt
                        + using_directives_opt
                        + global_attributes_opt
                        + namespace_member_declarations;

var global_attribute_target = new NonTerminal("global_attribute_target");

global_attribute_target.Rule = ToTerm("field") | "event" | "method" | "param" | "property" | "return" | "type";

global_attributes_opt.Rule = MakeStarRule(global_attributes_opt, null, global_attribute_section);
global_attribute_section.Rule = PreferShiftHere()+  "[" + global_attribute_target + colon + attribute_list + comma_opt + "]";

attribute_target_specifier_opt.Rule = Empty | attribute_target + colon;
attribute_target.Rule = ToTerm("field") | "event" | "method" | "param" | "property" | "return" | "type";
attribute_arguments_par_opt.Rule = Empty | Lpar + attribute_arguments_opt + Rpar;
attribute_arguments_opt.Rule = MakeStarRule(attribute_arguments_opt, comma, attr_arg);
attr_arg.Rule = identifier + "=" + expression | expression;

right
