/Sean McCauliff/:
I have a schema file where I define two complex types and one of the
complex types defines an element with the type of the other complex
type. When I write an instance file the enclosed element is in an
empty namespace instead of being defined in the name space of the type
or of the enclosing element. See instance_a.xml and schema_a.xsd
below.
[...]
If I change the schema so that the bType is defined as an element
instead. Then "b" is not in the http://eslug.net namespace.
Element "b" _is_ in the "http://eslug.net"; namespace - all
top-level/global components have the 'targetNamespace' of the schema
they are defined in.
schema_b.xsd
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://eslug.net";
xmlns="http://eslug.net";
>
<xsd:element name="b">
<xsd:complexType >
<xsd:attribute name="anotherattr" type="xsd:string" use="required" />
</xsd:complexType>
</xsd:element>
[...]
I would rather use schema a, but elements of "bType" only seem to show
up in the empty namespace forcing me to use schema_b.
Is this a bug or there some misunderstanding with how namespaces are
assigned to compexTypes in xml schema?
You may take a look at "3 Advanced Concepts I: Namespaces, Schemas &
Qualification" <http://www.w3.org/TR/xmlschema-0/#NS>, "3.1 Target
Namespaces & Unqualified Locals", "3.2 Qualified Locals". So as far
as I understand you just need to set
|elementFormDefault="qualified"| on the <schema> element.
You may also see how the {target namespace} of an element
declaration (for example) is determined from its representation
<http://www.w3.org/TR/xmlschema-1/#element-element>:
If the <element> element information item has <schema> as its
parent, the corresponding schema component is as follows:
{target namespace} The ·actual value· of the targetNamespace
[attribute] of the parent <schema> element information item, or
·absent· if there is none.
[...]
otherwise if the <element> element information item has
<complexType> or <group> as an ancestor and the ref [attribute] is
absent...
{target namespace} If form is present and its ·actual value· is
qualified, or if form is absent and the ·actual value· of
elementFormDefault on the <schema> ancestor is qualified, then the
·actual value· of the targetNamespace [attribute] of the parent
<schema> element information item, or ·absent· if there is none,
otherwise ·absent·.
