See XML Schema Part 2 sectoin 4.3.6:
 
whiteSpace is applicable to all
<http://www.w3.org/TR/xmlschema-2/#dt-atomic> .atomic. and
<http://www.w3.org/TR/xmlschema-2/#dt-list> .list. datatypes. For all
<http://www.w3.org/TR/xmlschema-2/#dt-atomic> .atomic. datatypes other =
than
<http://www.w3.org/TR/xmlschema-2/#string> string (and types
<http://www.w3.org/TR/xmlschema-2/#dt-derived> .derived. by
<http://www.w3.org/TR/xmlschema-2/#dt-restriction> .restriction. from =
it)
the value of whiteSpace is collapse and cannot be changed by a schema
author; for  <http://www.w3.org/TR/xmlschema-2/#string> string the value =
of
whiteSpace is preserve; for any type
<http://www.w3.org/TR/xmlschema-2/#dt-derived> .derived. by
<http://www.w3.org/TR/xmlschema-2/#dt-restriction> .restriction. from
<http://www.w3.org/TR/xmlschema-2/#string> string the value of =
whiteSpace
can be any of the three legal values. For all datatypes
<http://www.w3.org/TR/xmlschema-2/#dt-derived> .derived. by
<http://www.w3.org/TR/xmlschema-2/#dt-list> .list. the value of =
whiteSpace
is collapse and cannot be changed by a schema author. 
 
And the schema for schema documents:
 
  <xs:simpleType name="normalizedString" id="normalizedString">

    <xs:annotation>

      <xs:documentation

           =
source="http://www.w3.org/TR/xmlschema-2/#normalizedString"/>

    <xs:restriction base="xs:string">

      <xs:whiteSpace value="replace" =

    </xs:restriction>

  </xs:simpleType>
  <xs:simpleType name="token" id="token">

    <xs:annotation>

      <xs:documentation =

Subject: whiteSpace facet



Hello,

 

My questions are regarding White Space Normalization during Validation
http://www.w3.org/TR/2004/REC-xmlschema-1-20041028/structures.html#d0e165=
4.

 

1.	Is there a "default" value for the whiteSpace facet for xsd:string,
xsd:normalizedString and xsd:token? 

2.	What is the value of the whiteSpace facet for xsd:string? I assumed
it was 'preserve'. Is it? 

3.	What is the value of the whiteSpace facet for xsd:normalizedString?
I assumed it was 'replace'. Is it? 

4.	What is the value of the whiteSpace facet for xsd:token? I assumed
it was 'collapse'. Is it? 

 

For example, if I have an element of type xsd:normalizedString and in =
the
XML instance the value of that element contains newline characters =
should I:

a.	Expect an error/warning because the newline character is not in the
lexical space of xsd:normalizedString? 

b.	Expect the newline to be replaced with a space before validation
proceeds? 

c.	Something else? 

 

I'd go for "a" if the (implied?) "default" value for the whiteSpace =
facet
was "preserve".

I'd go with "b" if the answer for question #3 was that the value is (or =
is
implied to be) "replace".

 

But I just don't know.

 

Can you please point to the relevant section(s) in the XML Schema 1.0
recommendation that supports your answer?

 

Thank you.

 

Shlomo.
