[Zope] Acquisition breaking my tal:attributes="href ..." (I think)

How can I circumvent this apparent effect of aquisition?
I have a Zope Page Template like so (for a cable TV company Website):
1 <ul tal:repeat=
2 "package python:root.services.digital_tv.packages.objectValues('Cable Package')">
3 <li><a href="HREF"
4 tal:attributes="href package/feature_list/absolute_url"
5 tal:content="package/title_or_id">PACKAGE TITLE OR ID</a>
6 </li>
7 </ul>
'Cable Package' is a very simple folderish ObjectManager ZClass.
My only problem is in line 4. Because all the Cable Package objects acquire the "feature_list" ZPT object from their common parent directory ("packages"), absolute_url resolves to the following in every iteration:
~/services/digital_tv/packages/feature_list
This is no good. I want HREF in the different iterations of the "package" repeat variable to resolve to paths specific to the current Cable Package object, e.g.:
~/services/digital_tv/packages/gold/feature_list
~/services/digital_tv/packages/silver/feature_list
~/services/digital_tv/packages/platinum/feature_list
(Where gold, silver, and platinum are Cable Package objects within folder "packages".)
The actual, aquired feature_list ZPT (in the "packages" folder) in turn calls the individual Cable Package's channel_list method. It all works great when I call the correct URLs directly, because "here" is properly defined in the feature_list template as below:
<table tal:repeat="channel here/channel_list">
<tr>
<td tal:content="channel/title_or_id">TITLE OR ID</td>
<td tal:content="channel/number">000</td>
</tr>
</table>
So, how do I get line 4 in the first snippet to stop resolving to the URL of the acquired feature_list, and instead return the Cable Package-specific URL (gold, silver, platinum)?
Thanks so much for caring enough to read this far!
