Structured content is information or content that is organized in a predictable way[1] and is usually classified with metadata.
XML is a common storage format, but structured content can also be stored in other standard or proprietary formats.
When working in structured content, writers need to build the structure of their content as well as add the text, images, etc.
The structure must be valid according to the standard being used, and it is often enforced by the authoring tool.
