Hi,

We are implementing a new CSS engine for Batik. The new engine is
complaining
about: text-alignment-BE-11.svg and text-i18n-BE-09.svg. The error is on
'glyph-orientation-vertical' and 'glyph-orientation-horizontal'.

According to the CSS2 spec, "4.3.7 Angles"

"Their format is an optional sign character ('+' or '-', with '+' being the
default) immediately followed by a <number> immediately followed by an angle
unit identifier."

That means that '0' is not valid.

RECOMMENDATION:

I think we have two options:

[A] fix both tests and be aware that '0' is not valid for those properties,
which I think is not really nice from a user point of view. It also means
that the upcoming SVG validator will complain about that.

[B] Ask the CSS WG to add the following sentence in "4.3.7 Angles":

"After the '0' angle, the unit identifier is optional."

BTW: The CSS WG has already put such a statement in "4.3.2 Lengths"

I do prefer [B]

Thierry.
