SoftQuad's XMetaL 3 has been described as the Number 1 Choice for developing XML content applications. It has found a home in both industry and educational facilities.
Some of the reasons for this are:
Support of WC3 XML Schema
Flexible Development Environment
Scripting Support
The figure below shows an example XMetaL environment including the example business letter in Structure and Document views.
To compare the environment appearance, click FrameMaker Environment.
