I want to update the value in XML based on attribute value using XSLT below is the Input and Output XML

In this example, I want to append hard-coded value in the input string. 

Input XML
---------

```xml
<MyInfo isSurname="true">
    <name sysid="0">Google</name>
</MyInfo>

```

Output XML
----------

```xml
<MyInfo isSurname="true" surname="Drive">
    <name sysid="0">Google Drive</name>
</MyInfo>

```

For every input name surname will be same. so when the attribute isSurname is true we need to add "Drive" as surname
