ID/IDREF 验证占用的内存太多。请尝试减小 ID 和 IDREF 属性的数目。重新排列文件，以便具有 IDREF 属性的元素出现在它们引用的元素之后，这也可能有帮助。

ID/IDREF validation consumed too much memory. Try reducing the number of ID and IDREF attributes. Rearranging the file so that elements with IDREF attributes appear after the elements which they reference may also be helpful.
