This document serves as a detailed specification and reference of the Issuu Markup Language (IML).

An IML layout descriptor is a well-formed XML document; however, this specification makes no attempt to explain the fundamentals of XML. It is assumed that the reader is familiar with basic XML concepts and syntax. You can learn more about XML through the Wikipedia entry on XML and the XML page on the W3C site.

This specification does not deal with the compilation of skin libraries. You may refer to the Skinning section for more details on this topic.
