 Classes as Records
 ------------------
 
+.. index:: :> (coercion)

 We allow the definition of *Structures with Inheritance* (or classes as records)
 by extending the existing :cmd:`Record` macro. Its new syntax is:
 
 .. cmdv:: Record {? >} @ident {? @binders} : @sort := {? @ident} { {+; @ident :{? >} @term } }
 
-   The first identifier `ident` is the name of the defined record and
-   `sort` is its type. The optional identifier after ``:=`` is the name
-   of the constuctor (it will be ``Build_``\ `ident` if not given).
-   The other identifiers are the names of the fields, and the `term`
+   The first identifier :token:`ident` is the name of the defined record and
+   :token:`sort` is its type. The optional identifier after ``:=`` is the name
+   of the constuctor (it will be :n:`Build_@ident` if not given).
+   The other identifiers are the names of the fields, and :token:`term`
    are their respective types. If ``:>`` is used instead of ``:`` in
    the declaration of a field, then the name of this field is automatically
    declared as a coercion from the record name to the class of this
-   field type. Remark that the fields always verify the uniform
+   field type. Note that the fields always verify the uniform
    inheritance condition. If the optional ``>`` is given before the
    record name, then the constructor name is automatically declared as
    a coercion from the class of the last field type to the record name

 Substructures

+.. index:: :> (substructure)

 Substructures are components of a class which are instances of a class
 themselves. They often arise when using classes for logical
 properties, e.g.:
