GDL Attributes
A GDL attribute is a keyword and value pair. The value is a piece of data, and the keyword is simply a tag that is used to identify the piece of data. Arbitrary keyword and data pairs are allowed as long as the GDL syntax rules are followed.
The following code example shows a GDL attribute.
*Weight: 330 pounds
In the preceding example, "*Weight" is the keyword, and the "330 pounds" string is the value.
