XBRL document names.

Document names must match {base}-{date}[_{suffix}].{extension}.

XBRL Document Documentname Format
Instance {base}-{date}.xml
Schema {base}-{date}.xsd
Calculation Linkbase {base}-{date}_cal.xml
Definition Linkbase {base}-{date}_def.xml
Label Linkbase {base}-{date}_lab.xml
Presentation Linkbase {base}-{date}_pre.xml
Reference Linkbase {base}-{date}_ref.xml

Note: Although the Reference Linkbase file is a valid attachment type, at the moment it is not used.

The {base} on the instance filename should, but need not, begin with the registrant's ticker symbol or other mnemonic abbreviation.

The {date} must denote the ending date of the period. If the instance document is a prospectus or other report whose period is indefinite, {date} should match the filing date.

For example, a Form 10-Q covering the period ending September 30, 2009 has {date} = 20090930; and a 485BPOS filed on January 23, 2010 has {date} = 20100123.

The {base} and {date} on other files in the submission should, but need not, be the same as that used for the instance in the same submission.

REMARK: File names are case sensitive, and since January 2011, uppercase characters have been permitted.
