•element — XML elements

•element tag returns an element function for the XML tag tag. Call it with attributes on the left and children on the right, as in ["r":10] circle "". An empty right argument, "" or ⍬, gives no children. The result is a keyed vector with tag, attrs and children entries. Notebooks display it as HTML. In that HTML, the text of a script or style element isn’t escaped, as browsers require. A script element can hold JavaScript for the page. XML and SVG covers element trees.

Errors: DOMAIN for invalid tag or attribute names.
