> Ran into an issue when trying to multiple two elements of type unsignedByte
> together in a `dfdl:occursCount`. It is causing a cast exception trying to
> convert java.lang.integer to a java.lang.short. I was able to work around it
> by casing once of the bytes as an integer ` dfdl:occursCount="\{ ../value1 *
> xs:unsignedInt(../value2) }”`. Attached is a tdml demonstrating the error.
