Just having some problems with XML Capitalization. I am required to produce the following xml namespace using a XSLT File:\[code\]<?xml version="1.0" encoding="ISO-8859-1" ?>\[/code\]However, after being processed by my XSLT Engine the declarations changes the capitalization of ISO to iso.\[code\]<?xml version="1.0" encoding="iso-8859-1" ?>\[/code\]My Question were:\[code\] 1). Is/Are there any significant difference between these two declarations? 2). Is is possible to retain the capitalization of ISO?\[/code\]Thanks in advance
