I am lacking essential information to understand your setup:

 * at one place, you say that "standard_html_header" is
   in a ZClass

 * at another place, you say, it is placed in a folder.


Thus, what is the (exact) relationship between the
ZClass (more precisely, the respective ZInstance),
the folder and the "standard_html_header".

Furthermore, to understand "PARENT", you must consider
the URL that let to your object.
If this URL went through the folder immediately before
hitting "standard_html_header" (or probably another
object that uses "standard_html_header") then
PARENT[0] is *this* folder and therefore,
anything defined by it takes preceedance over
things that come from the ZClass.
