There are two different identity transformations. One is the logical
identity transformation that creates a new document with the same logical
structure (grove) as the input document. The other is the literal,
byte-wise identity transformation that creates a document with the same
physical structure (bit pattern) as the input document. I would be amazed
if the XSL specification supported the latter, because it would require a
very large amount of rarely useful information to travel from the parser
to the grove and into the output.

I would urge that a "markup editor" like SPAM is a different sort of tool
from a transformation language. You COULD put them together, but that
would put an unreasonable burden on implementors.
