http://core.netbeans.org/plans/features34.html#%22New%22%20wizard%20should%20hide%20read-only%20filesystems%20from%20you

is supposed to exist, but it does not, because the
HTML reads:

<a name=""New" wizard should hide read-only
filesystems from you">"New" wizard should hide
read-only filesystems from you</a>

(and a href= is similar).

I guess core/www/plans/plan-index.xsl is probably
to blame. Maybe it needs to substitute weird chars
with underscores or #XX URL escapes or something.

Note that *any use* of
disable-output-escaping="yes" is prone to generate
malformed output and cause all sorts of weird
problems. You probably never need to use this
scary flag. The makeReference template is mostly
worthless because you can use

<a href="{some-xpath-expr-here}">content</a>

instead.
