Content type: text/plain
Description: Sample PHP for XUL form generation and validation
Class: HV WDDX Metadata
Generates XUL and HTML forms based on XML config.
Author: By
Last change: Use 'file' and 'implode' instead of 'file_get_contents' for older php versions.
Put '<?xml' in echos instead of inline, to avoid parser problems.
