Properties don't get generated

[jeremycoppey]

I have a object HTML5 tag that I want to use in a UI5 application as a custom control. <object data="helloworld.mp4" name="audiotrack" type="audio/mp4" ><param name="controller" value="true" /></object> The data/name/type attribute of the Object tag are not generated as properties in the custom controller Is this normal behavior?
