Cannot find the user specified XSLT stylesheet '%1'. The PDF indexing process could not find the proper sort location for '%1', so the term has been dropped from the index. The build failed due to problems encountered when sorting the PDF index. Please address any messages located earlier in the log. Index entry '%1' will be sorted under the "Special characters" heading. %1 %1 %1 Ignoring index-see '%1' inside parent index entry '%2' because the parent indexterm contains indexterm children. Ignoring index-see-also '%1' inside parent index entry '%2' because the parent indexterm contains indexterm children. There is an index term specified with start="%1", but there is no matching end for this term. Add an index term in a valid location with end="%1". There are multiple index terms specified with start="%1", but there is only one term to end this range, or the ranges for this term overlap. Ensure that each term with this start value has a matching end value, and that the specified ranges for this value do not overlap There are multiple index entries found to close the index range for "%1". Ensure that any index term with start="%1" has only one matching end term with end="%1". A topic reference was found with href="". Please specify a target or remove the href attribute. The topic reference href="%1" could not be found. Please correct the reference, or set the scope or format attribute if the target is not a local DITA topic. Found an index term with end="%1", but no starting term was found for this entry. Font definition not found for the logical name or alias '%1'. Attribute set reflection cannot handle XSLT element %1. The index term '%2' uses both an index-see element and %1 element. Convert the index-see element to index-see-also.
