libxml2: Wrong separator in XML_CATALOG_FILES?

[Hartmut Goebel]

Hi,

I just discovered that libxml2 sets the search-path-specification for
variable "XML_CATALOG_FILES" using space as separator, which is very
uncommon. The documentation for libxml2 does not state which separator
to use, while the docbook-tutorial [1] has an example using colons.

So I'm curious whether the space is correct.
