This Lint rule should also detect and warn about unexpected empty annotations, especially for variable inputs:

Given these examples:

    <string name="spark_testing_1">Hi <annotation variable="foo"/></string>
    <string name="spark_testing_2">Hi <annotation variable="foo"></annotation></string>
    <string name="spark_testing_3">Hi <annotation variable="foo"> </annotation></string>
    <string name="spark_testing_4">Hi <annotation variable="foo">!</annotation></string>

only the last two will be able to "replace" the span content.
