Elements

The first character of an element label is used to encode its type. In a few instances, the second character is also used for that purpose. With the exception of the character(s) used to encode type, a label may include, in arbitrary order: letters, digits, and the two special characters ":" and "_" . Only the first 11 characters of a label are significant; all others are ignored. Labels are case sensitive, so "o" , "O" , "o1" and "O1" are four distinct elements. Note that type encoding is not case sensitive; the elements "o" and "O" both have the same element type.

The following is a complete list of available element types.
