<b:include/> and <b:includable> Example

The Includable
<b:includable id='list'>
        <b:loop values='data:foo' var='item'>
        <li>
            <data:item/>
        </li>
        </b:loop>
</b:includable>
Calling Includable 'list' with Data-Alias
<ol>
<b:include data='{ foo: ["Qux","Quux"] }' name='list'/>
<b:include data='{ foo: ["Corge","Graul"] }' name='list'/>
<b:include data='{ foo: ["Garply","Waldo"] }' name='list'/>
</ol>
Result
    1. Qux
    2. Quux
    3. Corge
    4. Graul
    5. Garply
    6. Waldo

With data-alias we can process multiple data with same format and get same result to avoid repeating typing same code again. The data with foo will be forwarded to <b:includable> tag and processed in <b:loop> tag with variable name item transform into <data:item/>.

The Includable With Child
<b:includable id='list' var='parent'>
    <b:include data='parent' name='list2'/>
</b:includable>
<b:includable id='list2'>
<b:if cond='data:foo'>
        <b:loop values='data:foo' var='item'>
        <li>
            <data:item/>
        </li>
        </b:loop>
<b:elseif cond='data:bar'/>
        <ol>
        <b:loop values='data:bar' var='item'>
            <li><data:item/></li>
        </b:loop>
        </ol>
</b:if>
</b:includable>
Calling Includable 'list' with different data name
<ol>
<b:include data='{ foo: ["Qux","Quux"] }' name='list'/>
<b:include data='{ bar: ["Corge","Graul"] }' name='list'/>
<b:include data='{ foo: ["Garply","Waldo"] }' name='list'/>
</ol>
Result
    1. Qux
    2. Quux
        1. Corge
        2. Graul
    3. Garply
    4. Waldo

In this example, data with different name and various string forwarded to <b:includable> with a name 'list' and variable 'parent', transform into group data:parent and gave to next <b:includable> with the name 'list2'. Conditional Statement is there to test which group and process with matching statement.
