Re: [xmlc] WML and getElementById() bug

Your fix for WML getElementById() works! Thanks!

When compiling from HEAD, we noticed there is a missing import in
/xmlc/xmlc/modules/xmlc/src/org/enhydra/xml/lazydom/html/NameNodeListImpl.java
It is missing the w3c Element class.

I would be interested in seeing a 2.2.7 official build come out with
the WML fix in it.

Thanks Jacob,
