are the two required elements for the Data Object Type description: </div>
<div align="left" style="text-indent:35.4pt;text-align:justify;margin-top:12pt;">
*The <font face="Courier New">dataObjectTypeID</font> uniquely identifies the group, within the scope of the Producer-Archive Project, for reference purposes and is given as <font face="Courier New" size="2"><span style="font-size:10pt;">L0DATAOBJECT</span></font>
in this example. It is defined in the XML schema as <font face="Courier New">xsd:string</font>.</div>
<div align="left" style="text-indent:35.4pt;text-align:justify;margin-top:12pt;">
*The <font face="Courier New" size="2"><span style="font-size:10pt;">dataObjectTypeOccurrence</span></font> is required and specifies the number of instances of this <font face="Courier New">DataObjectType</font> that should be present in the Group (TBC). This
may be expressed as one, or more, or as a range of values. This number may not be known at the time of specification. In the case of a unique value, the minimal occurrence and the maximal occurrence values will be the same.</div>
<div align="left" style="text-align:justify;margin-top:12pt;">As for the <font face="Courier New">groupTypeOccurrence</font><font face="Courier New">,</font> it is defined in the XML schema as type <font face="Courier New">occurrenceType</font> (see section
4.1.5 before).</div>
<div align="left" style="text-align:justify;margin-top:12pt;">Table 4-5 shows an occurrence of the <font face="Courier New">groupType</font> of exactly one. A more complete discussion is presented in section 4.3</div>
<div align="left" style="text-align:justify;margin-top:12pt;">The optional <font face="Courier New">dataObjectType</font><font face="Courier New">Description</font> provides the ability to have a meaningful description as to what the Data Object means. It is
defined in the XML schema as <font face="Courier New">xsd:string</font>.</div>
<div align="left" style="text-align:justify;margin-top:12pt;">Table 4-5 does not show all the PAIS defined elements that may be present in a <font face="Courier New">dataObject</font><font face="Courier New">Type</font>. </div>
<div align="left" style="text-align:justify;margin-top:12pt;">The Data Objects may be encoded (the description is the same as for the group encoding, see section 4.1.5), may be related to other elements in the MOT (see section 4.5.2 for Association Type description).
</div>
<div align="left" style="text-align:justify;margin-top:12pt;">The format may also be described. This information could be used on the Archive side to perform validation for example.</div>
<div align="left" style="text-align:justify;margin-top:12pt;">If the Data Object is composed of different types of files (for example a header along with a set of measures), then the dataObjectTypeFileOccurrence may be used.</div>
