Sorry, the other one simply defined GK_ATOMS.  That doesn't really do much =P

Of course I forgot to bump the IID. Consider that done.

formaction and formtarget patches are in bug 566160 and bug 566064.
Please, implement only formmethod and formenctype in this bug.

Part 1: Implement the attributes and use them

Based on comment 5, these patches need some tweaking (removing some parts).

Be careful with NS_IMPL_ENUM_ATTR_DEFAULT_VALUE. It is assuming the enumerated value is limited to only known values like input.type. When I wrote this macro I was thinking all enumerated values would have to be limited to known values. However, this is clearly not the case [1]. I had to open a bug to have input.type limited to only known value [2] (for backward compatibility) and someone did that for button.type [3].
I hope most enumerated attributes will be limited to only known values. Anne looks to agree with this idea which lets me think it's not completely non sense.

For this bug, you can use the current macro thus not respecting the specifications. You can also create a new macro or add a new parameter to not limit to only known values like:
#define NS_IMPL_ENUM_ATTR_NOT_LIMITED(_class, _method, _atom) \
  NS_IMETHODIMP                                                           \
  _class::Get##_method(nsAString& aValue)                                 \
  {                                                                       \
    return GetEnumAttr(nsGkAtoms::_atom, nsnull, aValue);               \
  }   
[...]

and in nsGenericHTMLElement::GetEnumAttr, you change:
  if (attrVal && attrVal->Type() == nsAttrValue::eEnum) {
    attrVal->GetEnumString(aResult, PR_TRUE);
  } else {
    AppendASCIItoUTF16(nsDependentCString(aDefault), aResult);
  }
for:
  if (attrVal && attrVal->Type() == nsAttrValue::eEnum) {
    attrVal->GetEnumString(aResult, PR_TRUE);
  } else if (aDefault) {
    AppendASCIItoUTF16(nsDependentCString(aDefault), aResult);
  } else if (attrVal) { // when not limited to only known value, there is no default value
    attrVal->ToString(aResult);
  }

Good news, you can forget comment 8, the specs have changed and formmethod, formenctype, method and enctype are now limited to known values.

You need to handle the case when aOrigin is null.
And also add testcases for that.

This is a bit evil. nsFormEvent has nsIContent* originator.
Could you just change that to nsGenericHTMLElement, and then there is no need 
for the extra static_cast

I agree that originator will always be nsGenericHTMLElement* but I think making originator nsGenericHTMLElement* wouldn't be better because we will have to include nsGenericHTMLElement.h in widget/public/nsGUIEvent.h or force all cpp files including nsGUIEVent.h to include nsGenericHTMLELement.h. Both solutions are not doable, are they? Maybe we could create a nsFormEvent.h file which will need cpp files including it to include nsGenericHTMLElement.h but that may be a bit too much just to prevent a static_cast, right?

I'm taking the ownership of this bug considering we want it for ff4 and David finished his internship and, according to jst, he may be on vacation now.

Bug 566160 and bug 566064 may be landed before landing this one. There is no hard dependency but the patch may not apply easily.

You don't need to #include anything to be able to use it in nsGUIEvent.h
Just have class nsGenericHTMLElement; somewhere in the nsGUIEvent.h

Patch v2

Could you change the type of the originator.
static_cast from nsIContent without any checks is error prone.
What if some code later starts to use  .originator with non-html elements?
If we change its type, whoever needs it for non-html will have to
change the type and check also other usage.

This line can be changed only by adding 'class nsGenericHTMLElement':
  nsIContent *originator;\

But this one needs the class to be defined AFAIK:
  originator(nsnull)
