Updated DTD declaration

Following correspondence from CrossRef, this allows the TDM information to be included in the main xml
Updated DTD declaration

Further to correspondence with CrossRef, allows TDM information to be added into the main deposit without CrossMark info
Added TDM data back into main deposit

According to instructions from CrossRef:
The metadata in the fundref and TDM-only deposit is correct but you also need to include the namespace prefix 'ai' in the schema declaration, so instead of:

<doi_batch version="4.3.2" xmlns="http://www.crossref.org/doi_resources_schema/4.3.2"
xmlns:fr="http://www.crossref.org/fundref.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.crossref.org/doi_resources_schema/4.3.2 http://www.crossref.org/schemas/doi_resources4.3.2.xsd">

you should use:

<doi_batch version="4.3.2" xmlns="http://www.crossref.org/doi_resources_schema/4.3.2"
xmlns:fr="http://www.crossref.org/fundref.xsd"
xmlns:ai="http://www.crossref.org/AccessIndicators.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.crossref.org/doi_resources_schema/4.3.2 http://www.crossref.org/schemas/doi_resources4.3.2.xsd">

If the TDM metadata is being submitted in a metadata deposit, the ai:program section should be inserted above the <doi_data> tag for example (note that the <lic_ref_data> tag is not used here) :

<publisher_item>
<identifier id_type="doi">10.7554/eLife.00178</identifier>
</publisher_item>
<ai:program name="AccessIndicators">
<ai:license_ref applies_to="vor">http://creativecommons.org/licenses/by/4.0/</ai:license_ref>
<ai:license_ref applies_to="am">http://creativecommons.org/licenses/by/4.0/</ai:license_ref>
<ai:license_ref applies_to="tdm">http://creativecommons.org/licenses/by/4.0/</ai:license_ref>
</ai:program>
<doi_data>
