consider making the match attribute default to '/*' for p:add-attribute etc.

[gimsieke]

In 1.0, only p:insert has a default of '/' for the match attribute, and p:label-elements defaults to . For most other steps with a match option, this option is required and does not have a default value. I find myself using match="/" most of the time, at least with p:add-attribute. Will it harm to make match default to '/' for p:add-attribute and several other steps listed below? The reason is: it reduces verbosity (a bit) without introducing too much arcane magic.

step	currently has default?	proposed default
p:add-attribute	no	'/*'
p:delete	no	pobably none
p:hash	no	'/*' (unless p:hash gets a select option that allows hashing string values calculated from the select expression)
p:insert	yes	'/*'
p:label-elements	yes	'*'
p:make-absolute-uris	no	probably none
p:rename	no	'/*' (not sure about this)
p:replace	no	probably none
p:set-attributes	no	'/*'
p:string-replace	no	'/*'
p:unwrap	no	'/*'
p:uuid	no	'/*'
p:wrap	no	/ (not sure about this)
p:www-form-urlencode	no	probably none

Proposed changes are boldface.

Would be great to have more defaults. Definitely /* for p:add-attribute, p:rename and p:unwrap (as you suggest).

For p:string-replace though /* will basically always result in a XD0001 error. Something like /*/text() would be more useful for the simple cases.
