+/**
+ * Mapping of legacy taggable resources to their tag property name and variant
+ *
+ * Before the introduction of iTaggablev2 the CDK defined a `tags` property on constructs
+ * which contained the tagManager, however in cases where the resource itself contained a
+ * property named 'tags', the CDK would create a `tagsRaw` property to represent that CFN tags property.
+ *
+ * Upon the introduction of iTaggablev2, the CDK now uses the `cdkTagManager` property to manage tags.
+ * This mapping of legacy resources is used to preserve the legacy behavior of applying tags so customers
+ * who previously were tagging these constructs using `myConstruct.tags.setTag('key', 'value')` will
+ * continue to be able to do so, without breaking changes.
