What ZEND_ACC_ALLOW_STATIC is supposed to do

Hi, I was looking at the documentation for DOMDocument::loadHTML() [1] that mentions the following: > This function may also be called statically to load and create a DOMDocument object. The static > invocation may be used when no DOMDocument properties need to be set prior to loading. However, this can’t be done in strict mode [2]: > Strict Standards: Non-static method DOMDocument::loadHTML() should not be called statically in > … This behaviour seems to be intended when ZEND_ACC_ALLOW_STATIC is used [3] and can be fixed by using ZEND_ACC_STATIC instead. My questions: 1) Is that the right kind of fix? 2) Is ZEND_ACC_ALLOW_STATIC meant to be used only for BC? If not, why are we raising strict errors?
