Description

Currently, outputs in Falcon process is optional which is fine.

<xs:element type="outputs" name="outputs" minOccurs="0">
<xs:annotation>
<xs:documentation>Defines outputs of the workflow
</xs:documentation>
</xs:annotation>
</xs:element>

but the contents of this should have atleast one event:
<xs:complexType name="outputs">
<xs:sequence>
<xs:element type="output" name="input" maxOccurs="unbounded" minOccurs="0">
</xs:element>
</xs:sequence>
</xs:complexType>

Otherwise, oozie throws exception:
