I'm trying to figure a pattern facet with my .xsd file. I want to only accept values that begin with 'E_ _' or 'N_ _' .
Right now I have the values under the enumeration a its looking for EEE or NNN, but I need to open it up to begins with E or N. I think I need to create a pattern facet but I'm unsure.
I'm having a hard time figuring out the syntax.
Also, if you have any references that I could use for syntax on these type of cases that would be great too.
