Structured Content, as the name implies, is information that is written
in reusable blocks or components.
Certain types of information lend themselves more readily to structure than others. Product or technical information, information for training, and marketing datasheets are classic examples of content that can be organized in recognizable blocks of information. By contrast, content that is more fluid such as marketing content or brand-oriented content often lends itself less easily to repeatable structures.

Structuring content eliminates the problem of writing and translating
the same information over and over again.
Businesses that structure content properly are realizing enormous cost savings, efficiency gains and business benefits.
To take advantage of the benefits of structured content, most organizations today
are adopting one of the XML standards that have been developed to make adoption easier.
Standards such as S1000D, MIL-SPEC and ATA iSpec 2200 are being used for civil and defense aviation documentation around the globle.
Before such XML standards were available, organizations had to develop their own XML standard called a “custom DTD.”
The adoption of structured authoring is an education process that involves people, process and technology changes.
