## Package org.apache.tomcat.util.descriptor.web Description

This package contains Java objects that represent complex data structures from the web application deployment descriptor file (`web.xml`). It is assumed that these objects will be initialized within the context of a single thread, and then referenced in a read-only manner subsequent to that time. Therefore, no multi-thread synchronization is utilized within the implementation classes.
