18.1 Introduction (ODF pt 1, public review 1)

Dear all,

The spec has:

----
The values of attributes and elements are often described as datatypes. These datatypes either are datatypes defined within [xmlschema-2], or are defined by this specification itself. Dataypes for which no [xmlschema-2]  datatype does exist are expressed in the schema by [xmlschema-2]  datatypes which have additional constrains. These constrains  are either specified in the schema, or in this specification.
----

* "described as datatypes" -> "described as having datatypes" ?

* constrains -> constraints (x2)

* "does exist" -> "exists"

* the last sentence is redundant, especially if the earlier one is tightened up (e.g. "this specification itself" --> "the normative prose of this specification")

More generally, is this paragraph true? Aren't some XSD type used without additional constraints? Aren't some datatypes defined (or at least implied) using regexps? And what about RDF?

- Alex.
