-In [`/permissive-`](../../build/reference/permissive-standards-conformance.md) mode, the compiler requires the **`template`** keyword to precede a template name when it comes after a dependent [`nested-name-specifier`](../../cpp/scope-resolution-operator.md).

 Compiler behavior has changed starting in Visual Studio 2017 version 15.8 under [`/permissive-`](../../build/reference/permissive-standards-conformance.md) mode. The compiler requires the **`template`** or **`typename`** keyword to precede a template or type name when it comes after a dependent *`nested-name-specifier`*. For more information, see [Name resolution for dependent types](../../cpp/name-resolution-for-dependent-types.md) and [Templates and name resolution](../../cpp/templates-and-name-resolution.md).

+## Remarks
+
 The compiler raises C7536 whenever the *`.ifc`* file has been tampered with. The header of the module interface contains an SHA2 hash of the contents below it. On import, the *`.ifc`* file is hashed, then checked against the hash provided in the header. If these don't match, error C7536 is raised:

 > *Identifier*: a forward declaration of an enum can only use a simple identifier
 
+## Remarks
+
 The C++ Standard doesn't allow declaring an opaque enumeration using a qualified-id. An opaque enum declaration specifies the name and the underlying type, but doesn't list the enumerators or their values.

 The following example generates C7742:
