Adding common attributes to docbook

[absent_carlo]

I'm trying to add some common attributes to docbook's dbpool.mod file to be used with effectivity. I was told to replace:


<!ENTITY % local.common.attrib "">

with

<!ENTITY %local.common.attrib
"NewAttrib CDATA #IMPLIED">

That seems to work, but it only works for one instance--how would I add another common attribute, say NewAttrib2? Is there any other section of the .mod file that needs to be updated?

If anyone could help me out or lead me to some doc that could better explain it, I'd appreciate it.

Thanks a million,

Carlo
