+/**
+ * IDrmFactory is the main entry point for interacting with a vendor's
+ * drm HAL to create drm plugin instances. A drm plugin instance
+ * creates drm sessions which are used to obtain keys for a crypto
+ * session so it can decrypt protected video content.
+ *
+ * The 1.2 factory must always create 1.2 IDrmPlugin interfaces, which are
+ * returned via the 1.0 createPlugin method.
+ *
+ * To use 1.2 features the caller must cast the returned interface to a
+ * 1.2 HAL, using V1_2::IDrmPlugin::castFrom().
+ *
+ * The IDrmFactory hal is required because all top-level interfaces
+ * have to be updated in a minor uprev.
