		// description:
		//		A DOM Element creation function. A shorthand method for creating a node or
		//		a fragment, and allowing for a convenient optional attribute setting step,
		//		as well as an optional DOM placement reference.
		//
		//		Attributes are set by passing the optional object through `dojo/dom-attr.set`.
		//		See `dojo/dom-attr.set` for noted caveats and nuances, and API if applicable.
		//
		//		Placement is done via `dojo/dom-construct.place`, assuming the new node to be
		//		the action node, passing along the optional reference node and position.
		// tag: DOMNode|String
		//		A string of the element to create (eg: "div", "a", "p", "li", "script", "br"),
		//		or an existing DOM node to process.
		// attrs: Object
		//		An object-hash of attributes to set on the newly created node.
		//		Can be null, if you don't want to set any attributes/styles.
		//		See: `dojo/dom-attr.set` for a description of available attributes.
		// refNode: DOMNode|String?
		//		Optional reference node. Used by `dojo/dom-construct.place` to place the newly created
		//		node somewhere in the dom relative to refNode. Can be a DomNode reference
		//		or String ID of a node.
		// pos: String?
		//		Optional positional reference. Defaults to "last" by way of `dojo/domConstruct.place`,
		//		though can be set to "first","after","before","last", "replace" or "only"
		//		to further control the placement of the new node relative to the refNode.
		//		'refNode' is required if a 'pos' is specified.

		//		Create a DIV:
		//	|	require(["dojo/dom-construct"], function(domConstruct){
