Version Attribute
The IEEE standard requires that the API Instance be accessible through a DOM Object. The standard also requires the DOM object to have an attribute named version. The value of the attribute represents the version of the API Instance. The value assigned to the attribute is required to consist of a period-delimited string containing major and minor release values as whole numbers. To indicate that the API Instance is built in conformance with the IEEE Standard, the first three characters are required to be "1.0". If an implementation wants to add additional characters to the value, to represent internal versioning information, then the fourth character is required to be another period-delimiter. An example would be "1.0.", with a period following the zero.
