Re: [xml-dev] XML Schema complex type constraint question

Oops, found 2.1.1 sample in 2004 posting on  xmlschema-dev:

  Subject:    [xml-dev] XML Schema complex type constraint question    
                                                                       






XML Schema spec
section 3.4.3 Constraints on XML Representations of Complex Type
Definitions
http://www.w3.org/TR/xmlschema-1/#d0e7923

does specify in section 2.1
2 If the <simpleContent> alternative is chosen, all of the following must
be true:
2.1 The type definition ˇresolvedˇ to by the ˇactual valueˇ of the base
[attribute] must be one of the following:
2.1.1 a complex type definition whose {content type} is a simple type
definition;
2.1.2 only if the <restriction> alternative is also chosen, a complex type
definition whose {content type} is mixed and a particle which is
ˇemptiableˇ, as defined in Particle Emptiable (§3.9.6);
2.1.3 only if the <extension> alternative is also chosen, a simple type
definition.

I created simple sample Schemata for 2.1.2 and 2.1.3 which work fine with
xmllint, see below.
I was unable to create a Schema sample for 2.1.1.
Can somebody provide a 2.1.1 sample Schema?


$ xmllint --schema 2.1.2.xsd 11.xml
<?xml version="1.0"?>
<str>abbbbbbbbbb</str>
11.xml:1: element str: Schemas validity error : Element 'str':
'abbbbbbbbbb' is not a valid value of the local union type.
11.xml fails to validate
$
$ xmllint --schema 2.1.3.xsd 11.xml
<?xml version="1.0"?>
<str>abbbbbbbbbb</str>
11.xml:1: element str: Schemas validity error : Element 'str': [facet
'maxLength'] The value has a length of '11'; this exceeds the allowed
maximum length of '10'.
11.xml:1: element str: Schemas validity error : Element 'str':
'abbbbbbbbbb' is not a valid value of the atomic type 'str10e'.
11.xml fails to validate

$ cat 2.1.2.xsd
