There are two issues: (a) whether LDP Patch invents a new language 
versus using a subset of SPARQL 1.1 Update; and (b) what choice of 
capabilities it should support.  My comment was addressing only the 
first of these two issues: I think it would be significantly 
advantageous to use a subset of SPARQL 1.1 Update rather than inventing 
a new language.

I did not look closely at the differences in capabilities supported by 
SparqlPatch [2] versus the current draft of LD Patch [1], so I do not 
know exactly how their capabilities compare, but my assumption is that 
they are different and the working group as a whole thought that the 
capabilities reflected in LD Patch [1] would be a better set to 
standardize than those in SparqlPatch [2].  For this reason my intent 
was only to push for using *some* SPARQL 1.1 Update subset, but let the 
working group decide what subset of capabilities that should be.  My 
assumption was that the working group would choose a subset similar to 
what is currently defined in LD Patch [1] (but using a subset of SPARQL 
1.1 Update instead of inventing a new language).

I hope that clarifies.

Thanks!
