Adding entity to books formatting

[Dmitry Morozovsky]

Dear colleagues,

I need an advice from dsl-fu-knowledgeable perswon ;)

Prodded by glebius@, I'm trying to add new entity svnref to generate a link to 
svnweb.

My quick patch stopped with an erro, while generating seems-to-be-correct 
content:

marck at woozle:~/FreeBSD/doc/en_US.ISO8859-1/books/porters-handbook> grep -6i 
svnref freebsd-versions.html
>Dec 12, 2011</TD

>10-CURRENT after defining boolean true/false in sys/types.h,
                      sizeof(bool) may had changed (rev <A
HREF="http://svnweb.freebsd.org/base?view=revision&revision=228444"
><TT
CLASS="SVNREF"
>228444</TT
></A
>).
                      <TT
CLASS="FILENAME"
>foofile</TT

The error is unknown element:

It seems I;ve missed something very similar -- what?

Thanks in advance!
