WML is very much like
XML. It is very strict compared
to HTML for instance, which means that when it is parsed and interpreted by the micro
browser there is not much room for error.
Just like in HTML, the language uses formatting tags surrounded by < and >. Most
tags have start tags <tag> and end tags </tag>. What's contained inside the
start and end tags are called elements. Some tags are so called empty-element, and have
tags with no content <tag/>.
Most elements may have attributes which further describe what is to be done with the
content within it. Attribute names must be in lower case, and the attribute values
must be enclosed in double quotes. Some elements require attributes, and some attributes
are optional. The general format of tags with attributes is <tag
attribute1="value">.
Variables may be present in the WML cards, and their general format is $(variablename)
A WML deck has a specific format, and must begin with the following XML and document type
declarations:
