Your XML is invalid per your schema. EISSDescriptorType has the following
definition:

<xs:complexType name="EISSDescriptorType">
  <xs:sequence>
    <xs:element name="Data" type="DataType"/>
    <xs:element name="BIFPlatform" type="BIFPlatformType" minOccurs="0" maxOccurs="unbounded"/>
  </xs:sequence>
  ...
</xs:complexType>

Which means that the Data element must be present in every EISSDescriptor
element.

I think you are confusing minOccurs="0" with empty content.

When you see something like this:

<EISS>
  <!-- No mentioning of EISSDescriptor -->
  ...
</EISS>

Then the minOccurs="0" is at play here. However, if you see something
like this:

<EISS>
  <EISSDescriptor/>
  ...
</EISS>

Then the element is present and the empty content must be allowed by the
element's type (EISSDescriptorType in this case). EISSDescriptorType clearly
does not allow empty content.
