Is it legal to have XML Text or CDATA that includes the zero character?
For example, is this legal?

char c = (char)0;
new Text(String.valueOf(c));

XOM's Verifier seems to say it's legal, whereas the Xerces and Saxon method XMLChar.isContent() suggest it's not legal.

Further, am I right in that a zero character must not appear in a surrogate?

Any advice or clarification? Thanks,
Wolfgang.
