【问题描述】：
我在 Elements.xml 中定义了一个内容类型，我想添加一个事件接收器。我的 Elements.xml 看起来像这样：
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<!-- Parent ContentType: Announcement (0x0104) -->
<ContentType ID="0x0104008a424de98660457481eb7d8ddb5161ee"
Name="News Posting"
Group="News"
Description="$Resources:NewsCTypeDescription"
Inherits="TRUE"
Version="1"
Sealed="TRUE"
>
<FieldRefs>
<FieldRef ID="{7EBC5918-CB79-440A-8DF3-480C6951C4EB}" Name="NewsExcerpt"/>
</FieldRefs>
<XmlDocuments>
<XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/events">
<spe:Receivers xmlns:spe="http://schemas.microsoft.com/sharepoint/events">
<Receiver>
<Name>ItemAdded</Name>
<Type>ItemAdded</Type>
<Class>MyAssembly.NewsItemEventReceiver</Class>
<Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
<SequenceNumber>10000</SequenceNumber>
<Synchronization>Synchronous</Synchronization>
<Data />
<Filter />
</Receiver>
</spe:Receivers>
</XmlDocument>
</XmlDocuments>
</ContentType>
</Elements>
奇怪的是事件接收器从不执行。我用 SharePoint Manager 2010 检查了架构，似乎 XmlDocuments 元素被完全忽略了？ 这是根据 SharePoint Manager 的内容类型 SchemaXml：
<?xml version="1.0" encoding="utf-16"?>
<ContentType ID="0x0104008A424DE98660457481EB7D8DDB5161EE" Name="News Posting" Group="News" Description="A News Posting" Sealed="TRUE" Version="1">

<Display>ListForm</Display>
<Edit>ListForm</Edit>
<New>ListForm</New>
</FormTemplates>
</XmlDocument>
</XmlDocuments>
</ContentType>
我也尝试添加一个 FormTemplates XmlDocument，只是为了看看它是否有效，但即使这也被忽略（我已将 ListForm 更改为 ListForm2，但 SchemaXml 未更改。
我已经删除了整个 Web 应用程序和内容数据库，以确保没有任何陈旧/卡住的东西，但结果仍然相同。
XmlDocuments 在 SharePoint 2010 中是否贬值？有哪些替代方案？
