Simple JavaFX XML editor with Canvas and GUI

Hi, So, as mentioned, the project is a desktop application written in JavaFX. It needs to be able to generate (marshall) a type of XML file and read (unmarshall) it. The type of XML is defined via the attached .dtd, and .xsd. It is called UIML and it stands for User Interface Markup Language - basically, an XML dialect for describing User Interfaces. A simple example looks like this: <uiml> <interface> <structure> <part class="Container" id="c1"> <part id="helloButton" class="Button"/> </part> </structure> <style> <property part-name="helloButton" name="style">red</property> <property part-name="hello" name="content">Hello World!</property> </style> </interface> </uiml> Additional information and examples can be read at the official specification - [login to view URL] But knowing UIML in detail is not required - once the java models are generated from the Schema, the required task is to create dialogs that capture the user input and marshal that into XML (UIML). The graphical representation of the this UI inside the editor does not have to be WYSIWYG - but rather WYSIWYM - i.e. the user has to see there is a button inside a 'container' and the button has a label "Hello World!" - Size, style, colors and whatever else does not have to be represented on the Canvas. Also, not all controls need to be implemented! I am not looking for a production ready code - your main task is to make the "structure", design of the solution and integrate it with at least one layout and one control. This is just the bare structure of the GUI + a bit of logic, but nothing much. Even the models are not correct, or I personally wouldn't do them in this way - I would rather use JAXB, or XMLBeans to generate the java classes from the XSD file (attached in previous email). So, have a look and let me know how much time do you think it's going to take you and are you still willing to go for the task. Let me know if you need more details and if you think/want to do something like this! Best Regards! P.S. Attached are also some screenshots of the current state - a dialog of insert button for example and then what a button should look like (approximately) on the canvas.
