Poet's writing having value (10)

I believe the answer is:

wordsworth

'poet's' is the definition.
(William Wordsworth, 1770-1850)

'writing having value' is the wordplay.
'writing' becomes 'words' (words is a kind of writing).
'having' means one lot of letters go next to another.
'value' becomes 'worth' (I've seen this in another clue).
'words'+'worth'='WORDSWORTH'

(Other definitions for wordsworth that I've seen before include "writer" , "Romantic poet" , "Poet (of the 20s)" .)

I've seen this clue in The Everyman puzzle in The Observer.
