    <xsd:documentation>Top level element for a metadata submission to Crossref. This element indicates the start and end of the XML file. The version number is fixed to the version of the schema. Be sure to set the name space attributes as shown above in order for the Xerces parser to process the instance correctly. For the purposes of parsing, you may also set xsi:schemaLocation to http://www.crossref.org/schema/4.x.x http://www.crossref.org /schema/4.x.x/crossref.xsd. A copy of the schema is located on the Crossref server at this URL and will remain constant for a given version of the schema. This location permits you to have a constant location for the schema for parsing without relying on a hardwired local directory on your development platform.</xsd:documentation>

<xsd:element name="timestamp" type="xsd:nonNegativeInteger">
  <xsd:annotation>
    <xsd:documentation>Indicates version of a batch file instance or DOI. timestamp is used to uniquely identify batch files and DOI values when a DOI has been updated one or more times. timestamp is an integer representation of date and time that serves as a version number for the record that is being deposited. Because Crossref uses it as a version number, the format need not follow any public standard and therefore the publisher can determine the internal format. The schema format is a double of at least 64 bits, insuring that a fully qualified date/time stamp of 19 digits can be submitted. When depositing data, Crossref will check to see if a DOI has already been deposited for the specific doi value. If the newer data carries a time stamp value that is equal to or greater than the old data based on a strict numeric comparison, the new data will replace the old data. If the new data value is less than the old data value, the new data will not replace the old data. timestamp is optional in doi_data and required in head. The value from the head instance timestamp will be used for all instances of doi_data that do not include a timestamp element.</xsd:documentation>

  <xsd:annotation>
    <xsd:documentation>A publisher identifier that can be used to uniquely identify the entity being registered. This identifier is a publisher-assigned number that uniquely identifies the entity being registered. This element should be used for identifiers based on publisher internal standards. Use identifier for a publisher identifier that is based on a public standard such as PII or SICI. If the item_number and identifier are identical, there is no need to submit both. In this case, the preferred element to use is identifier. Data may be alpha, numeric or a combination. item_number has an optional attribute, item_number_type. It is assigned by the publisher to provide context for the data in item_number. If item_number contains only a publisher's tracking number, this attribute need not be supplied. If the item_number contains other data, this attribute can be used to define the content. For example, if a journal is published online (i.e. it has no page numbers), and each article on the table of contents is assigned a sequential number, this article number can be placed in item_number, and the item_number_type attribute can be set to "article_number". Although Crossref has not provided a set of enumerated types for this attribute, please check with Crossref before using this attribute to determine if a standard attribute has already been defined for your specific needs. If a dissertation DAI has been assigned, it should be deposited in the identifier element with the id_type attribute set to "dai". If an institution has its own numbering system, it should be deposited in item_number, and the item_number_type should be set to "institution" If the report number of an item follows Z39.23, the number should be deposited in the identifier element with the id_type attribute set to "Z39.23". If a report number uses its own numbering system, it should be deposited in the identifier element, and the id_type should be set to "report-number" The designation for a standard should be placed inside the identifier element with the id_type attribute set to "ISO-std-ref" or "std-designation" (more generic label)</xsd:documentation>

    <xsd:documentation>The issue number in which an article is published. Only one issue name should be used for the issue. The issue number takes precedence over any other name. For example, if an issue has only a seasonal name, then the season should be listed in issue.
