Renamed docID attribute to refID of the <modificationRecord> so
the attribute name is consistent; docID attribute is deprecated but
remains for compatibility with older documents.
Added <correlatesWith>
and <correlation>
subelements of <uncertainty>
element to allow for multiple-dimensioned linear correlation of uncertainty of
selected functions and variables.
Added a new element,
<contactInfo>,
to replace the single
<address> element. This format
supports multiple ways to indicate the means of contacting the author of a document or
reference. <address> is deprecated but is retained for
backwards compatibility. This element also replaces the email and
xns attributes of
<author>.
Fixed typographical error in <ungriddedTableRef>
element: incorrect gtID attributed
corrected to utID.
Allowed multiple <author>
elements wherever one was allowed before.
Added a new tag, <isStdAIAA/>, to indicate a
variableDef refers to one of the standard AIAA variables.
Removed <[un]griddedTable[Ref|Def]> subelements of the <confidenceBound> element since this leads to
circular logic.
Changed SYSTEM ID to reflect new daveml.nasa.gov domain availability.
Removed e-mail URLs to protect privacy of individual contributors.
Added a new attribute, interpolate, to the <independentVarPts>
element to indicate whether the table interpolation should be linear or cubic spline
in the given dimension [modified to include quadratic in version 1.9].
Added a new tag, <isState/>, to indicate a
variableDef refers to a state variable in the model.
Added a new tag, <isStateDeriv/>, to indicate a
<variableDef> refers to a
state derivative variable in the model.
