我正在使用该Products.FacultyStaffDirectory产品来管理我网站中的联系人。
FacultyStaffDirectory当您处于编辑模式时，其中一种内容类型（即）在“分类”选项卡中具有描述字段。现在我需要删除描述字段并将其放在默认选项卡中。
为此，我使用archetypes.schemaextender产品来编辑该字段。特别是，我正在使用ISchemaModifier.
我已经实现了代码，但该字段仍显示在分类选项卡中。可能是我错过的东西。下面是代码：
这是包含我要修改的描述字段的类：

# Make this permission show up on every containery object in the Zope instance. This is a Good Thing, because it easy to factor up permissions. The Zope Developer's Guide says to put this here, not in the install procedure (http://www.zope.org/Documentation/Books/ZDG/current/Security.stx). This is because it isn't "sticky", in the sense of being persisted through the ZODB. Thus, it has to run every time Zope starts up. Thus, when you uninstall the product, the permission doesn't stop showing up, but when you actually remove it from the Products folder, it does.

这是我的 configure.zcml 中的代码：

有什么我缺少的吗？
