XStandard Pro is a WYSIWYG editor that runs in browser or desktop-based content management systems. Its toolbar is highly customizable and its rich API allows developers to extend the editor's functionality to meet unique content management needs. The editor manages rich, multilingual content of all types and uses CSS for formatting. The editor is fully keyboard accessible and generates clean, accessible XHTML Strict or 1.1 with no deprecated tags. It supports sophisticated editing options and uses Web Services (SOAP) for drag & dropping of files and folders, referencing files in remote libraries, communicating with third-party systems, and importing third-party content.
