hi,
IXBRL is last version of the XBRL Language, is different.
Standard XBRL is presented as a series of tags and numbers. iXBRL (inline XBRL), is a more recent version of the language, which allows financial information to be presented in a format that is both human readable and machine-readable. This is achieved by presenting the data (e.g. financial statements) in a normal document format but with XBRL "tags" embedded in the soft copy document.
my suggestion:
look at this post (on Nav Team Blog) and write a question about IXBRL for UK\Ireland (no documents
found in Partnersource to date).
