[Xsltforms-support] Insert not working in a empty element

[Ioan F. <mi...@gm...>]

Bonjour Alain,

I found this problem in the latest version - 578. Can be checked at any 
variant of insert. In the previous version that I tried it - 559 - this 
worked properly.

Drawback is especially noticeable in Chrome, which gives the error message:

" Uncaught TypeError: Cannot read property 'length' of undefined "


Merci beaucoup!

Ioan
