CSW filter Literal that contains whitespace characters do not work

[murrayh]

Hello,

Perform a CSW request using a Literal that contains a space character. The filter will fail to match any records.

I am working around this issue by replacing whitespace characters with the "singleChar" wildcard.

Below is an example CSW query. I will attach a relevant metadata record to this issue.

Cheers, Murray
