Models the SourceID attribute, which records the last modified time of the source file from which this class file was compiled.

This attribute only appears on classes, and does not permit multiple instances in a class. It has a data dependency on the constant pool.

This attribute is not predefined in the Java SE Platform. This is a JDK-specific nonstandard attribute produced by the reference implementation of the system Java compiler, defined by the jdk.compiler module.
