Use Case

A text in a zul is turned into a Label component.

<zk>
mylabel
</zk>

EL expression ${page} is also in the same situation.

In most cases, application developers don't intend to change such static text value dynamically since they write in a pure text.
The Label is largely used in almost every page e.g. in a form, the label for an input field doesn't change dynamically. Even there are only 5 labels on a page, but 100 users visit the same page will produce 5*100 unnecessary label components.

drawback

• if no dynamically change is needed, it's a waste of memory.

alternative

The native element like <n:span class="z-label">mylabel</n:span> can do the same work but it's more inconvenient.

Proposed Solution

turn the text into an HTML span, no Label Java component and Label widget, neither. Still apply z-label to keep the consistent style as ZK <label>.

<span class='z-label'>mylabel<span>

Consider to create a library property to determine such text conversion behavior ( to a Label or HTML span only)

This solution could cause a back-compatibility issue, if you find it, please list it.

advantage

1. save both server and client memory
