#1 Improve "const correctness"

[Markus Elfring]

Would you like to apply the advices from the article
"http://en.wikipedia.org/wiki/Const_correctness" to
your sources?
I suggest to add the key word "const" to the type
specifiers for parameters like the following.
- input (function "store")

- vn (functions "getAttr.+", "match.+")
vn, attrName (function "hasAttr")
vn, URL, localName (function "hasAttrNS")

Would you like to clarify any APIs as a documentation aid?

as far as I understand it, C doesn't support "const."

Where did you get this kind of knowledge?
"const" is a C key word.

hmmm... I checked again, it is in fact a C keyword. are you
suggesting that all #define should be declared "const."

No, not all. I indicated some candidates for an API clarification.
Do you see the situation that all interfaces might be affected?

Do you want to consider the C99 key word "inline" instead of "#define"?
