Description
After an upgrade from 6120 to 6210, a structure exception occurs when importing a Document Library LAR. I think this is a bug because exporting/importing worked in 6120.

Steps To Reproduce
1) Start a clean bundle of 6120.
2) Go to Control Panel > Documents and Media > Manage document types > Create a new test document type called TEST.
3) Shut down the portal.
4) In the database, replace the XSD value for the TEST structure (in the ddmstructure table) with this code:

<?xml version="1.0"?><root available-locales="en_US" default-locale="en_US"><dynamic-element autoGeneratedName="true" dataType="string" name="name" type="text"><meta-data locale="en_US"><entry name="label"><![CDATA[Name]]></entry><entry name="showLabel"><![CDATA[true]]></entry><entry name="required"><![CDATA[true]]></entry><entry name="predefinedValue"><![CDATA[]]></entry><entry name="tip"><![CDATA[]]></entry><entry name="width"><![CDATA[100]]></entry><entry name="fieldCssClass"><![CDATA[aui-w100]]></entry></meta-data></dynamic-element><dynamic-element autoGeneratedName="true" dataType="string" name="description" type="textarea"><meta-data locale="en_US"><entry name="label"><![CDATA[Long Description]]></entry><entry name="showLabel"><![CDATA[true]]></entry><entry name="required"><![CDATA[true]]></entry><entry name="predefinedValue"><![CDATA[]]></entry><entry name="tip"><![CDATA[]]></entry><entry name="width"><![CDATA[100]]></entry><entry name="fieldCssClass"><![CDATA[aui-w100]]></entry></meta-data></dynamic-element><dynamic-element autoGeneratedName="true" dataType="string" name="export-sequence" type="text"><meta-data locale="en_US"><entry name="label"><![CDATA[Export Sequence Number]]></entry><entry name="showLabel"><![CDATA[true]]></entry><entry name="required"><![CDATA[false]]></entry><entry name="predefinedValue"><![CDATA[]]></entry><entry name="tip"><![CDATA[]]></entry><entry name="width"><![CDATA[25]]></entry><entry name="fieldCssClass"><![CDATA[aui-w25]]></entry></meta-data></dynamic-element><dynamic-element autoGeneratedName="true" dataType="document-library" fieldNamespace="ddm" name="icon" type="ddm-documentlibrary"><meta-data locale="en_US"><entry name="label"><![CDATA[Icon]]></entry><entry name="showLabel"><![CDATA[true]]></entry><entry name="required"><![CDATA[false]]></entry><entry name="predefinedValue"><![CDATA[]]></entry><entry name="tip"><![CDATA[]]></entry></meta-data></dynamic-element><dynamic-element autoGeneratedName="true" dataType="string" name="package-refs" type="textarea"><meta-data locale="en_US"><entry name="label"><![CDATA[Package References]]></entry><entry name="showLabel"><![CDATA[true]]></entry><entry name="required"><![CDATA[true]]></entry><entry name="predefinedValue"><![CDATA[]]></entry><entry name="tip"><![CDATA[Comma delimited list of UUIDs that define the Packages that make up this Experience]]></entry><entry name="width"><![CDATA[100]]></entry><entry name="fieldCssClass"><![CDATA[aui-w100]]></entry></meta-data></dynamic-element></root>

5) Start the portal and go to Control Panel > Documents and Media > Manage document types > select TEST and verify that the metadata has changed.
6) Stop the portal and upgrade to 6.2 SP8.
7) Go to the Liferay site in the Control Panel and export a LAR of the Documents and Media portlet.
8) Create a new blank site and import the LAR.
9) The com.liferay.portlet.dynamicdatamapping.StructureXsdException occurs.

Expected result: the LAR would import.
Actual Result: The LAR does not import.
