Workday does not generate or validate XSLT. This document is created outside of Workday using non Workday technologies and applications.

XSLT attachment transformations are custom transformations that you create by using Extensible Stylesheet Language Transformation (XSLT). 

Custom XSLT is implemented in the Configure Integration System step. Remember the Steps to Implementing an EIB system: 

1.       Create Integration System 

2.       Configure Integration System 

3.       Launch Integration System 

4.       View Process Monitor Event 

When you Configure the Integration System you can create a new XSLT Attachment Tranformation. Here you upload your XSL or XSLT file into the EIB Configuration Task. It will then use it to execute the transformation.

Simply name the XSLT Attachment Transformation and provide any comments that are necessary. Browse for your file and attach it to the Workday Integration System.

There is a 30 MB limit for all attachments in Workday.
