Oops...  The documentation doesn't seem to mention this but any tag
attributes not recognised by Albatross are passed through to the
output unmodified.

The following passes a class attribute through <al-input>

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
>>> import albatross
>>> ctx = albatross.SimpleContext('.')
>>> ctx.locals.names = ['John', 'Terry', 'Eric']
>>> albatross.Template(ctx, '<magic>', '''
... <al-for iter="i" expr="range(len(names))">
...  <al-input nameexpr="'names[%d]' % i.value()" whitespace class="fancy">
... </al-for>
... ''').to_html(ctx)
>>> ctx.flush_content()
<input class="fancy" name="names[0]" value="John">
<input class="fancy" name="names[1]" value="Terry">
<input class="fancy" name="names[2]" value="Eric">

This does not directly solve your problem of needing to alter the
value of the class attribute, but you can always use
<al-if><al-else></al-if> to select between normal and error variants
of the tag.
