Distinguish tags from elements in the terminology

[tuukka]

Has it been a deliberate choice to treat the terms tag and element as synonyms in the spec and the grammar?

jsx/spec.emu

Lines 66 to 71 in d614ce7

	JSXElement :
	JSXSelfClosingElement
	JSXOpeningElement JSXChildren? JSXClosingElement
	JSXSelfClosingElement :
	`<` JSXElementName JSXAttributes? `/` `>`

I find this lack of distinction confusing when teaching JSX.

I think the following would be more clear and in line with the terminology used for HTML (e.g. Document.getElementsByTagName vs Document.getElementsByName):

      JSXElement :
        JSXSelfClosingTag
        JSXOpeningTag JSXChildren? JSXClosingTag

      JSXSelfClosingTag :
          `<` JSXTagName JSXAttributes? `/` `>`
