[wsbpel] Issue - 13 - Clarification

[Dieter Koenig1 <dieterkoenig@de.ibm.com>]

With the resolution of issue 13, several expression attributes have been
changed to nested elements. This is good.

According to the issue resolution, "this would affect <from>, <to>,
<propertyAlias>, and conditions".

It seems that the deadline and duration expressions in <wait> and <onAlarm>
have not yet been considered:

<wait standard-attributes>
    <for expressionLanguage="anyURI"> ... durationExpression ... </for>
    <until expressionLanguage="anyURI"> ... deadlineExpression ... </until>
    standard-elements
</wait>

<onAlarm>
    <for expressionLanguage="anyURI"> ... durationExpression ... </for>
    <until expressionLanguage="anyURI"> ... deadlineExpression ... </until>
    activity
</onAlarm>
