3.1.2: no lexeme for A and IMG tags parameters

[bkg2018]

The tag <img src="house.gif"/> is translated into <selfendnode, img>, loosing the src parameter.

Same goes for <a href="morePix.html"> which becomes <nodestart, a>, loosing the href parameter.

I would suggest cutting like this :

<nodestart, img> <nodeparam, src> <=> <text, "house.gif"> <nodeend>

and

<nodestart, a> <nodeparam, href> <=> <text, "morePix.html"> <nodeend>
