Can a link type contain '"' ? ;)
But seriously, if we move "dir" from <chroot> to an element (not that I would
like that), then <link> would be the only element left using attributes
(not counting <alfs>). So we might as well get rid of all attributes?

Or just keep them for <execute>, <configure>, <make> and <patch>?
And as far as <move>, <copy>, <link> and their different options are
concerned, how does:
sound, for example? Maybe not "options" (I'm thinking about <option> element
for something else I mentioned some time ago), but something like that...?
It would make adding a new options latter much nicer and easier, without
the need for new elements/attributes (like force="yes, please" ;).

Personally I prefer attribute, but is '"' allowed in a tag's attribute value?
<quote from="W3C REC-xml-19980210">
To allow attribute values to contain both single and double quotes, the
apostrophe or single-quote character (') may be represented as "'", and
the double-quote character (") as """.
This should mean yes, and it makes sense, but I have no idea why some
software doesn't parse those special entities in attribute's values (it
parses user-defined without the problem).

We can always add it later, so I would vote to use just <execute> for now.

Currently, in nALFS, order doesn't matter at all, except for <param> elements
which are used in the order of appearance.
I'm not sure that I see any benefits of ordering <base>, <name>, <target>
and similar elements within one.
IMHO, it's just important that they are inside. :)

What happened to <base>?
Should we rename it to <current_dir> or <working_dir> or something else?
