XAML text support
When you export artwork using one of the XAML-supported formats, some formatting of text objects may be lost because XAML does not support all text properties. If you have text objects in your Expression Design document and you select to export them to one of the XAML-supported formats, a warning icon will appear. You can then decide if you want to convert the text objects to paths, change the export format, or continue to export the text objects without the unsupported formatting.
