 # SLAXML
-SLAXML is a SAX-like streaming XML parser for Lua
+SLAXML is a pure-Lua SAX-like streaming XML parser. It is more robust than 
+many (simpler) pattern-based parsers that exist ([such as mine][1]), supporting code like `<foo test="5>7"/>`, CDATA nodes and comments and processing instructions.
+
+It is currently not a truly valid XML parser, however, as it allows completely invalid XML such
+as `<foo></bar>` to be parsed and reported as such. It is also not namespace-aware. See the "Limitations / TODO" section below for more details.
