LwDITA and {: xxx} syntax

Hi gang

--
I am wrapping up my testing on basic LwDITA element parity between XDITA and MDITA. Going well.
I have not been including in my Markdown code any of the following MarkedIt extensions. Just wanted to get feedback from the SC that they should be excluded. {: #heading-level} {: shortdesc} {: caption="table stuff" caption-side="top bottom"} {: caption="figure stuff" caption-side="top bottom"} {: video output="iframe" . . .} {: audio controls} {: note} {: .codeblock}
