How to use string constants with std::map

[Regina Henschel]

Hi all,

For import from OOXML, I need a map which has the shape preset type 
string as key and a vector of the angle strings of the cxn elements of 
that shape as value. I will extract this information from 
presetShapeDefinitions.xml file using XSLT. The map has total 187 rows.

How to write the map? In the past it would have been something like the 
following:

static const std::map<OUString, std::vector<OUString>> 
aConnectionSiteAngleMap{
     {"accentBorderCallout1",{"0","cd4","cd2","3cd4"}},
...
     {"wedgeRoundRectCallout",{"3cd4","cd2","cd4","0","cd4"}}
};

All strings are constants and neither the map nor the strings will ever 
change.

How do I have to write it now?

Kind regards,
Regina
