conditional in BPEL

["Durand, Jacques R." <JDurand@us.fujitsu.com>]

Chuck:

 

How about a modified version of the conditional statement markup in BPEL:

 

<if standard-attributes>

standard-elements

<condition expressionLanguage="anyURI"?>bool-expr</condition>

activity

<elseif>*

<condition expressionLanguage="anyURI"?>bool-expr</condition>

activity

</elseif>

<else>?

activity

</else>

</if>

 

The advantage I see is that it does not introduce a separate switch statement. It reuses the conventional if / elseif / else found in several programming lges and algorithmics.

And the entire statement is within a single xml element....

Any conditional statement, simple or switch-like, starts with <if>.

 

Now, I don't think we need a separate <condition> element.

We could have:

<if condition="...">

<elseif condition="...">

If necessary we could have an optional @exprlang in case the condition is not XPath.

 

opinion?
