<DL>
<DD>Compares two specified JsonML trees.
Two JsonML nodes are considered to be equal when the following conditions
are met:
- have the same type
- have the same attributes from the list of attributes to compare
- have the same number of children
- nodes in each pair of corresponding children are equal
Two JsonML trees are equal, if their roots are equal.
When two nodes are compared, only the following attributes are taken
into account:
TagAttr.BODY, TagAttr.FLAGS, TagAttr.IS_PREFIX, TagAttr.LABEL,
TagAttr.NAME, TagAttr.OP, TagAttr.TYPE, TagAttr.VALUE
Generally, the comparator does not care about debugging attributes.

The trees are not equal:
Tree1:

Tree2:

Subtree1:

-- equal to the corresponding subtree of the Tree2
Subtree2:
-- see Subtree1
If the trees are equal, null is returned.</DL>
