In a research publication issued last week by Gartner titled "XBRL Will Enhance Corporate Disclosure and Corporate Performance Management" (which can be purchased from Gartner here), the value of XBRL to CFOs and CIOs is pointed out.
Gartner says, "Extensible Business Reporting Language is an enabling technology that will significantly change the way financial information is reported, internally and externally. CFOs and CIOs need to understand the impact of XBRL, and plan for its adoption during the next three years."
