Part of this comes from its XML syntax and the only thing I find rather
clear in the Rec are the synopses, such as for instance:
<attribute
default = string
fixed = string
form = (qualified | unqualified)
id = ID
name = NCName
ref = QName
type = QName
use = (optional | prohibited | required) : optional
{any attributes with non-schema namespace . . .}>
Content: (annotation?, (simpleType?))
</attribute>
which is way clearer than its schema counter part:
<xs:complexType name="attribute">
<xs:complexContent>
<xs:extension base="xs:annotated">
<xs:sequence>
<xs:element name="simpleType" minOccurs="0"
type="xs:localSimpleType"/>
</xs:sequence>
<xs:attributeGroup ref="xs:defRef"/>
<xs:attribute name="type" type="xs:QName"/>
<xs:attribute name="use" use="optional" default="optional">
<xs:simpleType>
<xs:restriction base="xs:NMTOKEN">
<xs:enumeration value="prohibited"/>
<xs:enumeration value="optional"/>
<xs:enumeration value="required"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
<xs:attribute name="default" type="xs:string"/>
<xs:attribute name="fixed" type="xs:string"/>
<xs:attribute name="form" type="xs:formChoice"/>
</xs:extension>
</xs:complexContent>
</xs:complexType>
Why not follow the example of RELAX NG and define a non XML syntax
around the lines of the synposes?
