Of course, the tag prefix is something configured on a page-by-page
basis. In my own work, I might find "a" difficult to use, since it's
easily confused with the <a tag. A common UI Tag idiom is to use the
UI URL tag and <a tag together. So it would read something like this
----
<li><a href="<a:url action="Registration!input"/>"><a:text
name="index.registration"/></a></li>
-----
Maybe it's just me, but it seems like "a" is overloaded in an
expression like this.
----
<a2: seems like a slight improvement
<li><a href="<a2:url action="Registration!input"/>"><a2:text
name="index.registration"/></a></li>
----
My first alternative suggestion would be to use the prefix "ui", since
we often refer to them as the UI tags. So, we'd have something like:
-----
<li><a href="<ui:url action="Registration!input"/>"><ui:text
name="index.registration"/></a></li>
and
<ui:if test="task == 'Delete'">
<ui:submit value="%{getText('button.confirm')}"/>
<ui:reset value="%{getText('button.reset')}"/>
</ui:if>
<ui:else>
<ui:submit value="%{getText('button.save')}"/>
</ui:else>

But, personaly, I find <ui: a little clumsy to type with my stubby
little fingers, because of where the keys are positioned on a
QWERTY/US keyboard.
Now, I expect that, for consistency, we would be changing the URI to
"action" or "action2". Given that "a" is already being used by HTML,
the next most obvious one-letter abbreviation might be "n", being the
last letter in Action. But <n: is hard to type too.
We can't use "c", since that's a JSTL default. The next letter is t.
The token <t: is not so hard to type, and it also lines up with "tags"
in UI Tags. So, we'd have something like
<%@ taglib uri="/action2" prefix="t" %>
<li><a href="<t:url action="Registration!input"/>"><t:text
name="index.registration"/></a></li>
and
<t:if test="task == 'Delete'">
<t:submit value="%{getText('button.confirm')}"/>
<t:reset value="%{getText('button.reset')}"/>
</t:if>
<t:else>
<t:submit value="%{getText('button.save')}"/>
</t:else>
Of course, <saf: is pretty easy to type too.
<%@ taglib uri="/action2" prefix="saf" %>
<li><a href="<saf:url action="Registration!input"/>"><saf:text
name="index.registration"/></a></li>
and
<saf:if test="task == 'Delete'">
<saf:submit value="%{getText('button.confirm')}"/>
<saf:reset value="%{getText('button.reset')}"/>
</saf:if>
<saf:else>
<saf:submit value="%{getText('button.save')}"/>
</saf:else>
I just committed some pages to the Action2 MailReader app, using the
different prefixes.
