¶ dcc:comment
The element dcc:comment contains an unlimited count of optional files and comments, e.g. spreadsheets and graphics in any individual file formats.
The "comments" area contains individual information of a measurement process, providing further details about the measurement results. This area can be used optionally. Possible details are, for example, graphics of measurement curves, video or audio documents or individual measurement series in any file formats. The transmission of cost accounting in .pdf format for the execution of calibration activities is another conceivable use case.
These files are stored encoded in Base64 format in this area of the DCC.
¶ Tree structure
The tree structure of the dcc:comment element has the following appearance:
The element has the setting dcc:any, that means the number of elements is not limited and a namespace has not to be specified but can be specified.
¶ Extract from the XML schema: element definition "comment"
<xs:element name="comment" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
¶ Filling instructions
There are two examples for filling the dcc:comment element.
¶ Expample 1 for filling dcc:comment with XML-elements from a corresponding namespace/ schema
In this case a namespace will be specified, as an example we use the si-Namespace and use the D-SI XML schema within the dcc:comment-Element
<dcc:comment xmlns:namespace="https://ptb.de/si">
<si:real>
<si:label>MyLabel</si:label>
<si:value>13.37</si:value>
<si:unit>\degreecelsius</si:unit>
</si:real>
</dcc:comment>
¶ Expample 2 for filling dcc:comment
It is also possible to fill XML elements without a certain namespace/ XML schema:
<dcc:comment>
<ExampleStructure>
<ExpampleComment1>
<ExampleID>1234</ExampleID>
<ExampleCategory>Text 1</ExampleCategory>
</ExpampleComment1>
<ExpampleComment2>
<ExampleID>5678</ExampleID>
<ExampleCategory>Text 2</ExampleCategory>
</ExpampleComment2>
</ExampleStructure>
</dcc:comment>
