Quoting Andy Herrick:

"I also think we need to revisit, and standardize all the fx related jnlp fields.
right now I can see we have
1.) the extension declarer:
xmlns:jfx="http://javafx.com"
2.) the elements:
jfx:javafx-runtime (with attributes: version and href )
jfx:javafx-desc (with arguments: main-class, preloader-class, and sub-elements:
<jfx:javafx-desc><argument> (with arbitrary sub elements)
<jfx:javafx-desc><param> (with arguments name and value)
jfx:details, with it's sub element
jfx:certificate-path
3.) and the properties: "jnlp.fx=<version>", "jnlp.tk=jfx"

are there any more ?"
