    Description: 
Hi.

I'm using drools 5.1.0 together with .xdrl files. I encountered a possible bug in the AndHandler class when
parsing the following .xdrl file:

--cut here--
{code:xml}    
                <dro:pattern object-type="EMail">
                    <dro:and-constraint-connective>
                        <dro:field-constraint field-name="foo">
                            <dro:literal-restriction evaluator="!=" value="null"/>
                        </dro:field-constraint>
                        <dro:field-constraint field-name="foo.toLowerCase">
                            <dro:literal-restriction evaluator="==" value="test"/>
                        </dro:field-constraint>
                    </dro:and-constraint-connective>
                </dro:pattern>
{code}
--cut here--

Parsing this seems to fail when adding the package from xml:

{code}
Caused by: org.drools.compiler.DroolsParserException: org.xml.sax.SAXParseException: <and-constraint-connective> has an invalid parent element [[Pattern: id=null; objectType=EMail]]
        at org.drools.compiler.PackageBuilder.addPackageFromXml(PackageBuilder.java:304)
        at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:468)
        ... 142 more
{code}

According to the .xsd (4.0) this should be no problem. Looking at the OrHandler it seems that simply the 
PatternDescr is missing from the validParents.

Also tried to disable xml validation with:

{code}
System.setProperty("drools.schema.validating","false");
{code}

but with no luck. So find attached the _very_ complex patch that adds PackageDescr to the AndHandler :).
