ISO20022 XML Tags for Date Format and Payment also

Summary:

Hi,

I'm trying to create a custom disbursement payment template and am having issues with the datetime formatting in XSL version 1.0.

Seeded:

<CreDtTm>

  <xsl:value-of select="PaymentInstructionInfo/InstructionCreationDate"
/>

</CreDtTm>

Result -  <CreDtTm>2018-07-31T15:02:20+00.00</CreDtTm>

We need to remove the red highlighted so tried the following but it's not working. The format payment files has the error "Parse Error in format-dateTime function". I think the issue is with the syntax for the datetime format. Can somebody help with the correct format.

Custom:

<CreDtTm>

We also want to change Payment method should be TRF, but we are using this for Wire Payments.
