6.4 FieldServer XML Schema
The FieldServer XML schema is arranged as a tree structure consisting of a Root Element, multiple Child Elements
which define the Data_Arrays in the FieldServer , and one Sub-Child element per Child Element which define the
Data in the Data Arrays as well as the attributes of the data (e.g. validity). Attributes are used to specify the
parameters of the Elements in the tree.
Note that the Element Name is ALWAYS in lowercase.
The diagram shows the general format of the XML tree.
