DescribeFeaturetype response contains unexpected wrapper schema

[lgoltz]

The WFS is configured for GML 3.1 with disabled dynamic schema and static schema location:

    <GMLFormat gmlVersion="GML_31">
        <MimeType>text/xml; subtype=gml/3.1.1</MimeType>
        <MimeType>text/xml; subtype="gml/3.1.1"</MimeType>
        <MimeType>application/gml+xml; version=3.1</MimeType>
        <GenerateBoundedByForFeatures>false</GenerateBoundedByForFeatures>
        <GetFeatureResponse>
            <DisableDynamicSchema>true</DisableDynamicSchema>
            <SchemaLocation>../appschemas/test_gml311.xsd</SchemaLocation>
        </GetFeatureResponse>
        <!-- Genauigkeit auf 6 Stellen testweise aktiviert -->
        <DecimalCoordinateFormatter places="6"/>        
    </GMLFormat>

The referenced SchemaLocation test_gml311.xsd imports the GML 3.1 schema:

<import namespace="http://www.opengis.net/gml" schemaLocation="http://schemas.opengis.net/gml/3.1.1/base/gml.xsd"/>

The DescribeFeaturetype response [1] contains a wrappper schema instead of the original schema:

<schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://geobasis-bb.de/forstfoerderung/wald">
  <include schemaLocation="http://localhost:8081/deegree-webservices/appschemas/test_gml311.xsd"/>
  <import namespace="http://www.w3.org/2001/SMIL20/" schemaLocation="http://schemas.opengis.net/gml/3.1.1/smil/smil20.xsd"/>
  <import namespace="http://www.w3.org/2001/SMIL20/Language" schemaLocation="http://schemas.opengis.net/gml/3.1.1/smil/smil20-language.xsd"/>
</schema>

SMIL 2.0 is imported in https://schemas.opengis.net/gml/3.1.1/base/defaultStyle.xsd.

Expected behavior: The DescribeFeaturetype request returns the original schema test_gml311.xsd.
