The serialization spec (for 2.0) says that when indenting, whitespace may be
added only immediately before an (element) start tag or immediately after an
end tag. This means it can't be inserted between a comment and a text node.
Although there's no such rule in XSLT 1.0, the logic is the same; it's
generally unsafe. For example:

<date-of-birth>1832-01<!--I think it's a 1 but it might be a

If you add whitespace around the comment, the document becomes invalid
against the schema.

One could do better in some cases, for example for a comment that
immediately follows an end tag (or is separated from it only by whitespace);
but in the end, you have to decide how much effort to put into fine-tuning
the algorithm.
