XML Schema substitutionGroup isn't validated correctly by IDEA

Try run 'Validate' command which uses Xerces validation, if the problem
will not be reported then please file JIRA issue

Here's a simple XML schema:

<xsd:complexType name="objectType">
</xsd:complexType>

<xsd:element name="object" type="objectType"/>

<xsd:element name="test" substitutionGroup="object"/>

<xsd:element name="data">
<xsd:complexType>
<xsd:sequence minOccurs="0" maxOccurs="unbounded">
<xsd:element ref="object" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>


Here's a simple corresponding XML file

<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<object/>
<test/>
</data>

However, the "test" element shows up in red and the error is "Element test is not allowed here". However, it is allowed there by the substitutionGroup. Is there something wrong with my XML schema, or is this a bug in IDEA?

I have found the answer to my question. The element object must be abstract for it to work.
