Custom rule assembly has invalid XML resources

This occurs if a custom rule assembly has invalid XML resources describing its rules. The correct format is as follows:

<Rules FriendlyName="Customer Rules">
  <Rule TypeName="[The unqualified type name of the rule]" Category="[A category name such as Customer.Usage]" CheckId="[An identifier for the rule that is at least unique within the same category]">
    <Name>[Localized version of the type name, this is the rule name that appears in the UI]</Name>
    <Description>[A sentence describing the rule in more detail than the name].</Description>
    <Url>[A URL pointing to a documentation or info about the rule]</Url>
    <Resolution>[Format string for rule messages].</Resolution>
    <Email>[Email Address]</Email>
    <MessageLevel Certainty="[A number from 0 to 100]">[Error or Warning]</MessageLevel>
    <FixCategories>[NonBreaking or Breaking]</FixCategories>
    <Owner>[Rule owner name or group]</Owner>
  </Rule>
</Rules>
