Type:

A Type may be either of:

header:Describes the required XML header lines. Without questions, use the header in the section titled XML header. container:A container element has subelements but no text of its own. These are similar to the NeXus NXDL group type. floating-point number:  Elements of type floating-point number are obvious. In most cases, a unit attribute is required. This will be noted. string:Elements of type string are any valid string (non-whitespace) sequence.

Occurence:

The number of times a particular element may appear is described in the occurence column. A value of [0..1] indicates the element is optional but may appear one time. A value of [0..inf] indicates the element is optional but may appear an infinite number of times (also known as unbounded).

Attributes:

Attributes list the required or optional attributes of this element. Note that attributes must adhere to the well-formed [1] XML guidelines:

attributename="value"

where either single or double quotes surround the value. All attributes must have a value. Attributes may be given in any order.
