This document contains 10 sample questions about dynamic attributes in JavaServer Pages (JSP). Dynamic attributes allow JSP tags to accept arbitrary attributes that are not defined in the tag's Tag Library Descriptor (TLD). The questions cover how to configure dynamic attributes for different tag types (tag files, simple tags, classic tags) and what code is required to access dynamic attributes from within a tag.
