[xml] xmlSchemaParse function

[Luka Por <luka zrcalo si>]

Hello.

Library is great, but from version 2-2.6.20 to version 2-2.6.22 i 
discover same difference.

I using xmlSchemeParse(...) to validate document.
In version 2-2.6.20 xmlSchemaParse spends 4 seconds,  but now in version 
2-2.6.22 it spends 16 second (same in version 2-2.6.21).

I have another question.
Same documents have validation sheme(xsd). This validation sheme imports 
another sheme, but url include unsafe char (space). The validation 
failed because not valid uri type. Is any help here.
