Tree inconsistency between Changes-generated and Snapshot-generated

[hackerwins]

What happened:

There is an inconsistency between the Tree generated by Changes and the Tree generated by Snapshot. Although each Tree is supposed to maintain isomorphism, two discrepancies have been identified:

1. size for index calculation in the XML representation of the Tree is different.
2. attributes are different.

What you expected to happen:

It is necessary for the values of Trees generated in these two different ways to be the same.

How to reproduce it (as minimally and precisely as possible):
