parser: Fix entity check in attributes Don't set the "checked" flag when checking entities in default attribute values. These entities could reference other entities which weren't defined yet, so the check isn't reliable. This fixes a short-lived regression which could lead to a call stack overflow later in xmlStringGetNodeList. 2023-01-17 13:50:51 +01:00			`<!DOCTYPE doc SYSTEM "N" [`
