[TYPO3-english] TypoScript: conditional wrap question

[Michael Cannon]

The TypoScript below works as desired, but I feel there's a simpler way.

Any help? The successful helpers will be mentioned in an upcoming Acqal
Blogging post. Thank you!


Output

no page author or page email, then no tag

page author only exists
<meta name="author" content="Michael Cannon" />

page email only exists
<meta name="author" content="mc at acqal.com" />

both page author or page email exists
<meta name="author" content="Michael Cannon (mc at acqal.com)" />

    80 = COA
    80 {
        10 = TEXT
        10 {
            required = 1
            data = page:author
