 # Blink IDL Extended Attributes
 
 [TOC]
 
 ## Introduction
 
 The main interest in extended attributes are their _semantics_: Blink implements many more extended attributes than the Web IDL standard, to specify various behavior.
 
 The authoritative list of allowed extended attributes and values is [bindings/IDLExtendedAttributes.txt](https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit/Source/bindings/IDLExtendedAttributes.txt). This is complete but not necessarily precise (there may be unused extended attributes or values), since validation is run on build, but coverage isn't checked.

 Usage: `[URL]` can be specified on DOMString attributes that have `[Reflect]` extended attribute specified only:
 
 ```webidl
 [Reflect, URL] attribute DOMString url;
 ```
 
 You need to specify `[URL]` if a given DOMString represents a URL, since getters of URL attributes need to be realized in a special routine in Blink, i.e. `Element::getURLAttribute(...)`. If you forgot to specify `[URL]`, then the attribute getter might cause a bug.
 
 Only used in some HTML*ELement.idl files and one other place.
 
-### [NoImplHeader] _(i)_
-
-Summary: `[NoImplHeader]` indicates that a given interface does not have a corresponding header file in the impl side.
-
-Usage: `[NoImplHeader]` can be specified on any interface:
-
-```webidl
-[
-    NoImplHeader,
-] interface XXX {
-    ...;
-};
-```
-
-Without `[NoImplHeader]`, the IDL compiler assumes that there is XXX.h in the impl side. With `[NoImplHeader]`, you can tell the IDL compiler that there is no XXX.h. You can use `[NoImplHeader]` when all of the DOM attributes and methods of the interface are implemented in Blink-in-JS and thus don't have any C++ header file.

 ## Temporary Blink-specific IDL Extended Attributes
 
 These extended attributes are _temporary_ and are only in use while some change is in progress. Unless you are involved with the change, you can generally ignore them, and should not use them.
 
 ### [LegacyTreatAsPartialInterface] _(i)_
 
 Summary: `[LegacyTreatAsPartialInterface]` on an interface that is the target of an `implements` statement means that the interface is treated as a partial interface, meaning members are accessed via static member functions in a separate class, rather than as instance methods on the instance object `*impl` or class methods on the C++ class implementing the (main) interface. This is legacy from original implementation of `implements`, and is being removed ([Bug 360435](https://crbug.com/360435), nbarth@).
 
 
 ### [CachedAccessor] _(a)_

 Added to members of a partial interface definition (and implemented interfaces with `[LegacyTreatAsPartialInterface]`, due to [Bug 360435](https://crbug.com/360435)) when merging `.idl` files for two reasons. Firstly, these members are implemented in a separate class from the class for the (main) interface definition, so this name data is needed. This is most clearly _written_ as an extended attribute on the partial interface definition, but this is discarded during merging (only the members are merged, into flat lists of methods, attributes, and constants), and thus this extended attribute is put on the members. Secondly, members of partial interface definitions are called differently (via static member functions of the separate class, not instance methods or class methods of the main class), and thus there needs to be a flag indicating that the member comes from a partial interface definition.
 
 ## Undocumented Blink-specific IDL Extended Attributes
 
 *** note
 **FIXME:** The following need documentation:
 ***
 
 * `[PerWorldBindings]` :: interacts with `[LogActivity]`
 * `[OverrideBuiltins]` :: used on named accessors
-* `[ImplementedInPrivateScript]`, `[OnlyExposedToPrivateScript]`
