The above is simpler than XML and can be used in any text-editor. The intention is ease of use, and it reads from left-to-right, for those in most English-speaking countries, and from right-to-left for those in most Asian countries, or whatever direction your language reads.

The "<=:(Custom tag goes here)" is used to make the document human-readable, and to format the document, so that it is effectively watermarked. The WMMUL is a completely platform-independent Markup Language. It may have future developments if an open-platform is developed.
