Re: [xsl] Variable Scope

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

Ok, Templates are:
validate_base.xsl  (base template)
validate_sped.xsl  (imports validate_base; includes incl_GradAge.xsl)
incl_GradeAge.xsl (included file with MAX_DATE problem)

(much code has been removed)
Also, below you'll find comments for the LIST with the following syntax:
